Recently I have found that "International HTC One Now Receiving Android 4.3 Via OTA Update To Software Version 3.62.401.1"
I have also found a download link for download over the air download file.

Is your phone stock or do you have a custom ROM?
If custom ROM, you will need to have a stock ROM and stock recovery to successfully execute an OTA.
Are you S-OFF, if not you can not flash the OTA files.

AT&T phones must unfortunately be connected to the at&t network to receive ota update. Since you are not on the at&t network, I would recommend to convert your phone to another version that doesn't requires any specific carrier to receive update like the Developer edition.
To convert your phone to another version, you'll need to achieve S-OFF so you can change your CID number so you can flash another version RUU.
