chromecast SSDP discovery - Google Chromecast

Hi,
I'm trying to write an app that needs to discover the Chromecasts ip address. Since everything I've read indicates it uses SSDP, I have sent a UDP packet to the broadcast group address 239.255.255.250 on port 1900 as follows:
M-SEARCH * HTTP/1.1
MX: 5
ST: "upnp:rootdevice"
MAN: "ssdp:discover"
HOST: 239.255.255.250:1900
everything on my network except my chromecast responds on port 1900. Does anyone know if this packet is not sufficient to get a Chromecast to reply, or if I need to listen on a different port to 1900? I'm really struggling to get anwhere with this and I can't figure out why!

try port 8008 That seems to be used for ssdp in chrome

just tried that and no different unfortunately. I get a response from my router still, (192.168.0.1) but not from the chromecast.
I think 8008 is the http tcp port that is used for RAMP commands isn't it?

DIAL Protocol Spec says your Search Target header (ST) needs to be
urn:dial-multiscreen-org:service:dial:1

Take a look at the documentation here:
https://github.com/jloutsenhizer/CR-Cast/wiki/Chromecast-Implementation-Documentation-WIP
The current APIv2 actually uses mDNS to discover Cast devices.

That may only be the port that the CCast uses to respond....Try the other suggestions I was only guessing since that was what Chrome reported as ssdp for CCast....But like I said it may be the response port and not the port that elicits the CCast to respond with it's info!

Make sure that you open up the port on your computer's firewall, your router, and anything else that might have a say in your internet traffic.
I'm not going to explain it, but Google "port forwarding".
im in the campus dorms
i dont think i can do any port forwarding as i dont know how the whole lan thing is set up here
thanks
i am currently having the same problem ...i have forwarded the port 5900 on my router and opened up my firewall...could i possibly have to do something to the modem as well or could it be something else
i am on a I touch 3g slide and running windows xp home
i have also heard that port tunneling may be neccesary but i lack the knowledge to do so any help would be appreciated
its all about port forwarding because you have dynamic ip addresses on the LAN side and most likely you have a dynamic WAN ip also. Usually to do VNC you have to have a Public IP address. Home ADSL circuits provide one public ip address but out of a NAT pool so it will change. This could cause an issue unless you want to check the destinations ip address everyday. So instead of VNC to an ip address you can vnc to a host name. Dyndns provides a good service for free. So that solves the dynamic IP issue.
Now to the port issue. Since the internal LAN will assign each host a 192.xxx.xxx.xxx ip address (which are not publicly routed), you have to do port forwarding. To do this go to the command prompt (start>run>cmd) and type in "ipconfig /all" and press enter. Find the default gateway ip address (192.xxx.xxx.xxx). Type that into the web browser. That will log you into your router. I have a 2wire router provided by att so if you have different you will have to discover this on your on. Go to firewall settings and then add a new user-defined application. basically make a new application.
protocol tcp
port range 5900 (i believe that is right)
and then add it to the correct computer.
That should send all data on that port to that host.
Hope that has helped a little bit. if not, google it.

You may want to give up with that and try out PhoneMyPC. I'm not 100% sure of how they do their tunneling, but I can tell you I've tested it a few times and it always manages to get through even if I purposely change WAN ip addresses and I don't do any port forwarding for it.
It also runs way faster (albeit lower resolution, i think) and more fluidly than either of the RDP or VNC solutions I tried out. I'm very impressed with it so far. I can even jump online with it and pull up my security camera software and actually see the live video feed from it, all running on my PC at home, even just over a 3G connection.

Chromecast problem "but cant access the internet" on Belkin Router

Hi everyone,
I have a Beklin Share N300 router and trying to set up my chromecast on this network.
Everything works fine, i mean the set up process; chromecast can see the network, can connect the network without any problem but get this message on the screen:
ChromecastXXX connected to yournetwork, but cant access the internet.
Has anyone faced this problem before?
I appreciate for your comments

Im been having the same problem since yesterday morning. Ive been in contact with Google and they escalted my case but i havent heard back from them about it.
I had the same problem with my E4200v2 router. I just kept trying and trying from the chromecast app on my Samsung Galaxy S4 and after an hour it finally setup. Have patience and keep trying everything. Reference your router's manual for additional information you might need. Good luck!

did you try putting the CC in the DMZ?
I don't have the CC yet, so I don't know if it needs any ports open in your firewall. Is there any way to manually enter a private IP or DNS info?
From what you're describing, the Chromecast isn't getting the DNS information.

DMZ could be the solution. Try disabling AP isolation under your router's setup UI.
Sent from my SGH-M919 using Xparent Skyblue Tapatalk 2
The AP (access point) he probably doesn't have setup anyway since that's more for bridging.
I just don't know if CC needs any ports forwarded. He may want to see what IP is being assigned to his CC and then check the firewall logs to see if any traffic is being blocked by it. The DMZ on his router should place the CC in front of the router and thus let all traffic to and from it, which should, in theory, fix the DNS problem.
It maybe to worth a shot to port foward port 53, which is usually used for DNS. I don't remember if it was UDP or TCP or both. And sometimes you still need to port forward even when using the DMZ. It's lame, but router's just act funny sometimes.
====================
it just dawned on me, it might be that CC is getting it's internet access from the device that's getting the content. So, you may need to enable internet sharing on your PC. Although, I don't think this is the case.
I also was getting the "connected to wireless, but can't access the internet" What I determined is that the ChromeCast is NOT using the DNS servers provided by my DHCP server, it was trying to communicate to a different DNS (likely Google's own).
In my case, I had a firewall in place that prevented access to any DNS other than what I was providing in DHCP. Once I opened the restriction and allowed all DNS traffic, chromecast immediately connected.
Hope this helps someone else.

Interesting. In my case, it was the opposite. I had my laptop configured to use Google's DNS servers and I kept on getting the same "connected to wireless, but can't access the internet" message. I reset the DNS servers on my laptop and Chromecast immediately connected to the Internet.
anyone know which port/s does chromecast use
DMZ worked for me but i dont like putting devices on DMZ. Sounds like this is just a port forwarding issue and putting it on DMZ is an overkill.
Anyone knows which port/s does chromecast use???
I also have the Belkin N300 and was having the same trouble. What i did was a factory reset on my router and a firmware update in the router settings and now everything seems to be working fine as of now.
AP Isolation
Switching off AP Isolation fixed the issue for me. I had the same issue before I did this.

I tried this too, even porting, but no luck..
tried every single suggestion but cant figure out what is wrong.
What i understand from the replies; it needs some specific DNS. But when i change my DNS on my routers setting page different than provided my ISP, router itself doesnt connect to internet.
DMZ, MAC filtering, disabling Firewall, disabling AP, none of them work so far; with numerous combination of those...
I believe it shouldnt be that hard.. ?
Update: Placing it in DMZ took a couple of retries but have fixed the issue now.
Similar problem. Worked on the first setup. Then after two day a get "can't connect to internet" message. Tried factory resetting and putting in the DMZ. Nothing helps. Anyone?

I don't really have more suggestions. From what I know, the CC doesn't need any special DNS information because really all the CC is just a media player (although not exactly correct). When you cast something to it, the device (mobile device or PC) you're sending it a URL, which it then opens and can play. This is why it needs an internet connection. Tab casting is a little different. Thus, if it'll play on your mobile device or PC, you can play it on the CC (assuming the content is CC compatible). If there is not internet to the CC, then the DNS and ISP information is not being forwarded to the CC or it's not connecting to them; this assumes it's getting an private IP from the router and not being denied because of MAC filtering or something.
Over here I've got another problem. My current ISP forces me to use their DNS. Since the Chromecast has its own fixed Google DNS (8.8.8.8 & 8.8.4.4), the Chromecast is not allowed to connect to the internet.

Same here, I'm on a studentnet that uses a PPTP connection with their own DNS, so if I change the DNS I won''t have an internet connection, permanent. Not sure how to fix that.

Sent from my XT897 using XDA Premium 4 mobile app
I had the same issue with the original firmware (12072).
After leaving it connected a few days it eventually stayed connected long enough to download an update.
After restarting it, it applied the update.
On firmware 13300 it complains when it initially boots, then after about a minute or two it connects successfully.
So...
If you're rooted, use FlashCast to update to PwnedCast 1.0 (based on 13300)
If you're not root-capable or have no plans to root, set it up and leave it at the "but can't connect to the Internet" for a few days (just leave it powered by the power adapter), then power-cycle it, hopefully you will see it updating.

Chromecast network issues

Does anyone elses Chromecast wreak havoc on their network? My other devices slow down, and my router seems to occasionally go in and out. What might solve this? It's not a speed issue, as this doesn't happen when streaming on the computer or wii.
standing by this thread. My tablet phone and laptop all have expirienced this slow down. speed test is still showing a 25ms ping and 30mbps down, but youtube and play store are timing out on both my phone and tablet, and when trying to cast from any device, the entire thing lags out. then i lose the cast button...
haven't found a solution yet

When I set up the Chromecast for the first time, my router totally locked up. I rebooted it and haven't had any problems since. I am running an ASUS RT-AC66U w/ Merlin-ASUSWRT firmware.
I have a similar problem. I use my Chromecast and then my router chokes up till I reboot it.
My dlink router was from 2007 and chromecast would lock it up completely. Bit the bullet and bought a new router and haven't had any issues since.

Chromecast slowing my internet connection
Experiencing an issue kind of similar to the OP's. Basically while my Chromecast is plugged into the TV, even when not in use, it slows my internet connection. I normally get between 25mbps and 35 mbps down on a speed test and gaming as well as file downloads work great. As soon as I plug Chromecast in, my download speeds on a speed test drop to about 1.5mbps to 6mbps. All of a sudden online gaming is basically impossible due to ping spiking and downloading files becomes extremely slow. If I unplug the Chromecast my internet speeds return to normal. I don't know what Chromecast is doing, but something is taking it's toll on my network.
Rebooting the router (Linksys E1000 I believe) has down nothing to resolve the issue. Does anyone know what could be causing this? Is there a way to make Chromecast hibernate or something when it's not in use? Any information about what could be causing the issue or things to try would be helpful. Thank you
Corrected the issue
I was able to fix the issue. Turns out my Cable Modem has a built in router that my computer was plugged into. I also have a linksys (wireless) router that is connected here. The chromecast is connected to the linksys router. I unplugged my computer from the cable modem (router) and plugged them into the same router as the Chromecast (Linksys). This appears to have fixed the issue. Someone that is better with this stuff could probably explain why, but I just wanted to follow up.
Totally!
I had this problem too. I have a Chromecast, AppleTV, GoogleTV and Ouya all right next to each other, with the Chromecast in an "always on" state. Ever since plugging in the Chromecast, network performance on the AppleTV and GoogleTV has been unusably slow. Even VNCing into my desktop PC, which is hard-wired into my cable modem, was slowed down.
I unplugged the power on the Chromecast last night, rebooted the AppleTV and GoogleTV and voila they work wonderfully. Network performance on other connected devices seems to be much better as well.
Would having several wifi devices in close physical proximity be the cause, or is it more likely Chromecast's need to be "discoverable"?
FWIW my wireless router is an Xfinity modem.

Can you describe what happens in a little more detail?
Does your network get slow, does your Internet get slow, do your devices suddenly say there is no wireless network? Something else??
"Unusable" can mean a lot of things.

Hmm, Google says your RTN56U is compatible but to contact ASUS for assistance which I'm guessing means ASUS might have an beta or pre-release firmware that fixes the issue.

I'm having this same issue. I'm using an Asus rtn16 with tomato firmware by shibby. Quite frankly it's ridiculous that this is a problem for chromecast. My router is a newer model and it should be supported. My roku 3 is able to stream just fine off my WIFI. All I've been able to deduce thus far is that when casting, the wireless interface of my router seems to get ddosed in some way because when pinging the router wirelessly from other devices, the pings skyrocket up to 1000ms and it causes some packet loss. Ends up making the chromecast stream really badly and of course my other devices slow down. When pinging the router through a wired connection during this time, the pings are sub 1ms. So it seems that the chromecast wreaks havoc on the wireless interface for whatever reason. As I said before, no other devices in my home cause the same symptoms. I may try to see what I can gleam from sniffing the network with my alfa usb WIFI adapter which is able to capture everything going across the air in promiscuous mode. I'm not sure if a lower level wireless spectrum analyzer would be necessary but let's hope not. Or let's just hope Google gets this sorted! I realize that some have fixed this by switch routers, but I don't see that as an acceptable solution since no other devices have issues with my router.

Roku and Chromecast work in very different ways and therefore use the network in much different ways. Chromecast has a discovery protocol that Chromecast-enabled applications use to find Chromecasts on the network. This involves multicast packets, and while most routers handle and allow multicast just fine, some either are stupid/flawed or are shipped with "secured" default settings that block multicast traffic.
After discovery
What applications and content are you casting from?

Tried youtube, tab casting, and plex.
Youtube barely gets through a video. Tab casting works for a couple seconds, then chokes and loses the connection. Plex buffers every 5 seconds. I actually do notice ping rises to around 500ms when using plex on my galaxy note 8, when the client fetches chunks of video every 10 seconds or so from the server. i noticed that this happens over tcp, whereas tab casting sends a udp flood. but I'm not really sure what is 'normal' as far as the ping going up when the wifi is being used to capacity. I can imagine that saturating the network would do that. I know that plex will pull data in chunks as fast as it can. So that saturates the wifi for about a second or two for every chunk. But I guess for whatever reason, chromecast saturates it even more. Not sure if its because its udp or what, and I don't really know why that would make any difference.
So, streaming with anything else is ok, on both G & N modes, causing ping to go to around 500ms.
When streaming to CC, on both modes, ping can hit 3000ms at times and total packet loss.
I'll see if playing with any of the advanced wifi settings in the router can fix it.
Not sure this is relevant but I have seen a bunch of issues being reported by people using custom Router Firmware....
Not just here but on other sites as well...
Maybe it's just coincidence...

Your network bandwidth seems "bursty" - not a big deal for general data transfer, but definitely an issue for streaming where sustained throughput is important.
What's your signal strength on your Galaxy Note?
Can you increase the signal power on your router?
Also, check your router's orientation. Often times the internal antennae are designed to operate in specific orientations, so putting a router designed to stand upright on its side can drop the signal dramatically as the devices are no longer within the transmission cone/donut.

Good advice.
Remember that the WiFi bands (channels) are not exactly the same between countries. So if you're in a non-US country and your router happens to choose a channel that is not available in the US, Chromecast may not detect your wireless AP.
But Telus is Canadian, and Canada has the same WiFi channels as the U.S. (Canada and the U.S. necessarily share identical radio spectrum allocation).

Didn't know that. Thanks! Still applies to other countries though. I think Channel 13 is one of the channels that applies to Europe but not US. I should put it in the FAQ...
EDIT: Seems there's far less exclusion than I thought... but added a note in the FAQ just in case.

So I can get through the setup phase up until the Chromecast tries to connect to my wifi network. I get a message saying it couldn't connect, and when I click the link in the message it brings me to a page that mentions AP filtering, UPNP enabling and .NET 3.5. I checked and UPNP is enabled, and I can't find an option for AP filtering (I have the Actiontech V1000h). I am using a Macbook pro.

In some cases you have to go through a couple of times. I just reset my Chromecast to test a few things and had to go through the setup twice before it connected to my WiFi.
Chromecast in Canada, on Telus
A friend lent me his chromecast. He uses an iphone and Shaw cable. I use a Nexus 4, and have Telus as my internet provider.
It was a bear trying to get chromecast to work. Tried 5 separate days. Got it to work and i could watch netflix/youtube on it about 3 times and played with it for a couple of hours each. That's the success.
The fail is that I had to trouble shoot more then 4+ hours to get it to work those 3 times. Reboot the chromecast. Reboot the router. Reboot my Nexus 4. Try my wife's Nexus 4. Try the Nexus 7 tablet. It was a horrible experience. I got the AP recommendation like the earlier post in this thread. I tried that. Tried calling telus and signed into my router to check that those settings were correct. As far as I understand it's a gateway 11n wireless router.
So my conclusion is change my internet provider to Shaw unless someone has a smart solution to this problem. The router says it's a 50ghz signal? So it isn't the 2.4vs 5.0 ghz signal problem that I've googled and read about.
Please provide some brains to my situation. I've used all of mine up.

Still not fixed.
So I took the plunge and bought one. Maybe it'd be different than my friends. Looks like this is a me problem. The chromecast still doesn't work. I thought it might be the tv that it's plugged into? Maybe shielding the chromecast from the wifi? I don't know. Will trouble shoot with a different tv or a long hdmi cable that will get the chromecast out from behind the tv. Maybe that'll help.

TVs are great at blocking/scrambling radio signals.
Use the included HDMI extender. If that doesn't help (enough), get an HDMI extension and move Chromecast away from the TV. One of mine is on a 10-foot HDMI extension. The other is connected upstream of a another device that connects to my TV, so both of my Chromecasts are at least a foot away from its associated TV.

It could be a few things not related to the router directly but related in how the Router connects to your ISP.
So a couple of questions...
What kind of service is your ISP? (DSL, CABLE, OTHER)
What Public IP does your router report? (Usually found on the status page that shows connection data) If it starts off 192.168 then your Modem is doing a double nat translation and you need to call your ISP and tell them you want the Modem to be put into gateway mode and just pass a public IP to your router.
Does the CCast actually connect to the Router but not work or will it not connect at all period? If it doesn't connect at all it is possible you need to change the Security method used to WPA or WEP. To test shut off security alltogether and try to connect the CCast. If there is currently NO security try putting WPA on and trying again (but it should work on an open AP)

Service is Telus DSL.
Solution: I changed the security settings. It still tries to stop the CCast from talking to my phone once in a while, but I just log into my router and log into the firewall settings. The firewall settings are "high, medium, low, NAT". It started working once I started turning it off of NAT and onto Medium or High.
I don't know why this is the solution, but it is a solution. I suspect that either Telus will fix the prolbem for everyone else or this thread will become popular. Now CCast is coming to Canada. So either Telus fixes it or there'll be a lot of searching leading to this post.
As a reminder, a friend of mine on telus never toughed his firewall settings and never had a problem with using his CCast. Go figure.

Well if the Telus was set to NAT perhaps Double Nat Translation was the issue.
DO you have another router connected to your modem or is this one of those all in one Hybrids supplied by the ISP?

I have a friend that is struggling with this as well. While setting up the WiFi connection between the chromecast and the router (the Actiontec V1000H - which is a modem/router combo if that helps). The chromecast will see the WiFi, but it seems to time out while trying to connect to the router.
I did find a comment on a blog somewhere (sorry, I forget where) that suggests unchecking the "IGMP snooping enabled" option in the router (Advanced Settings>IGMP Setting). Once this was done, the chromecast connected to the WiFi without any issues and we were able to stream it without any issues.
However after going out for dinner we had major issues trying to connect to the WiFi on our phones and his laptop (laptop would try to connect to the WiFi but continually fail). It seems like this is a temporary fix at best.
The only permanent solution I can think of at the moment is to go buy a new router that is listed as having no issues on the chromecast compatibility list... Which kind of defeats the whole purpose of having the chromecast as an economic way to stream content to your big screen.
Buy a better router
I don't see why IGMP should have any affect on being able to login and connect.
I Can see it being a problem with streaming but not connection.
IS this an ISP provided Modem/Router? How many devices are connecting wirelessly?
Check settings for IGMP Proxy, Try changing that setting whatever it is but it should probably be disabled (Still don't think this would affect connection but it's worth checking)
Check if UPnP Is enabled (again not really connection related but it does need to be enabled for CCast)
I personally prefer to use a two device setup with separate Modem (in Bridge Mode) and Router....This way the Modem protects the router from the outside world and even if the Modem goes bad the Network still functions properly.
And I pretty much stay away from anything that isn't a Linksys or Netgear product as far as Routers are concerned.
There are a bunch of Actiontec models that are listed as incompatible with CCast on the google site so it's obvious that something about their firmware is not CCast friendly.
So the the previous poster may actually have made a good suggestion in the long run! LOL
I'm using the telus actiontech router with chromcast with no issues....
its a pretty crappy router though and it seems telus disabled the ability for bridge mode in the latest firmware... has anyone found a solution to this so i can buy a better router?

As long as double NAT doesn't cause you problems, you can
Assign the new router's WAN port to an address in the ISP router's LAN range
Set the new router's gateway to the ISP router's LAN address
Connect the two routers LAN port to LAN port
Have all your wired and wireless clients connect to the new router.

Consistent error on Netflix with Chromecast

Everytime I try to stream a movie to my Chromecast with Netflix, after a few seconds of watching I get this error ""we're having trouble playing this title right now. Please try again later or select a different title." I will typically get this error 5+ times after restarting over and over before finally being able to watch the movie/show uninterrupted. This happens with every video, and with any device I use to stream to the chromecast (Samsung S4, iPhone 5S, Dell laptop computer, ASUS TF700).
I've tried the following to remedy it:
1. Sign out all devices on Netflix
2. Factory reset the chromecast
3. Uninstall and reinstall the Netflix app on my Samsung S4
4. Updating to the newest version of Netflix app on my Samsung S4
Is anyone else having an issue, or has been able to fix it with steps in addition to what I've tried myself?
Thanks so much!

Are you having trouble with any other services like YouTube?
It might be something as simple as Chromecast having a marginal WiFi connection and not getting consistent streaming throughput. Try the HDMI extender.

I haven't had any issues with any other service: youtube, casting tabs from chrome, avia. It's only netflix which gives the issue. I don't have the HDMI extender on, so I can see if I can find it. It's worth a shot.
I also wonder if a defective chromecast could be the cause?

Given that your other services are working okay it's highly unlikely that a defective Chromecast is to blame. A defective Chromecast would show other problems, especially in other applications that use significant bandwidth, like Avia can.
You aren't using an alternate DNS, are you?

Not that I know of. I live in California so I haven't had a need to mess with any advanced settings to get things to work.

Okay that eliminates one possibility.
If you play it on your device (not casting to Chromecast), do you get the same problem?

Works fine on all other devices. Only gives the issue when I push the stream to the Chromecast.

Just for fun, can you shut down (or turn off WiFi) on all devices that can talk to Chromecast, then try with just one Chromecast-controlling device?
Beyond that I'm stumped.

I can try that when I get home today, but I'm pretty sure that won't do anything. The only other device I use to typically cast is my laptop, which is usually off in the evenings when I'm trying to watch.
Maybe its an issue with my cisco router.

Me too, just trying to cover all bases.
How "smart" is your router? If it's smart (or thinks it is) it might be denying the initial Chromecast traffic for some reason (looks like someone hogging 2.4 GHz bandwidth?). Possible checks - QoS, STP/loop detection, storm detection, IGMP-related features, parental control, bandwidth throttling.

While I consider myself fairly technically savy, about everything you mentioned in "possible checks" is well beyond my expertise. I have the most basic of cisco routers since I was being fairly cheap. Bought it for $50 a few months ago. No idea how smart it is, but for $50 I can't imagine it is. Can you point me to some specific checks I can run to narrow down the issue?

I should try running it at my friend's place with a different router to see if the router is really a problem.

That's a great test to try if you can. Also, if you tell me the model number of your router I can probably check online to see if there are any obvious "problem" settings.

I think I have this one:

I can definitely check when I get home to make sure.

If your router is like the E2400, it may allow using the same SSID name on 5GHz and 2.4GHz APs.
While I don't necessarily think that's your issue, it is good practice to have different names for the two AP bands.
You may want to try disabling WMM, based on what some folks reported as a fault in the Cisco WMM or conflict with Xfinity.
WMM is enabled by default, according to page 33 of the E-series manual.
If disabling WMM solves things, you could try enabling WMM and enable No Acknowledgement (this is disabled by default).
Just as a side note, the cheaper routers that have Fast Ethernet ports (such as the E1200) usually have little hope of achieving advertised 802.11n throughput, though most people don't have 150 Mbps Internet connections to begin with.

I will give this a shot tonight. Fingers crossed! Thanks so much for your help, I very much appreciate it.
OTA build 15250 is rolling out starting today that address's some Netflix issues.

UPDATE: I disabled WMM and did not have the problem after that. Watched a few videos without seeing the error once. That being said, I then re-enabled the option and the error did not reappear, so I'm unsure whether or not this was the fix. I don't think the new build was downloaded on my chromecast yet, so that wasn't the fix. In either case, I'm happy the problem is gone (for now). Will come back to update if I learn anything else.

Cool. Might be a weird thing like something is "floating" (like an uninitialized variable) so toggling the option fixes it by setting it to a good state.
