Video chat via Talk doesn't work

Hi, I tried to search but couldn't find any topic with the same issue, so please redirect/ let me know if I post in the wrong place.

Got my Nexus 4 for a week, and I noticed that I just cannot video chat via the Talk app. Anytime I initiate a video chat, or accept an invitation, I get kicked out of Wifi, the videochat stops, and I receive a "You can't videochat because of a network error". Wifi connects again immediately after that. Anything else is fine. Does anyone experience the same issue? Any suggestion? Thanks a ton!

I have no issue video chatting with Talk. Have you tried at a different location? Maybe it s an internet issue?
