The only person I used to video conference with was my girlfriend; her in her apartment, me in mine. We both would be logged onto our gmail accounts, using the video chatting feature. Nothing has changed in the last 2 weeks, but suddenly, the video chatting option has stopped working. Whenever I send an invite, and she accepts, we just get an error message that: "There was a communication error during your chat." I've made sure that nothing in our router settings or networking settings has changed. I don't know what on earth could be causing this. Can anyone point me in the right direction?
