Session Expiring between EVERY game

My session seems to expire between every single game. Like i play a game and cant honor because my session expires and i just get auto logged out and have to re-log in to get back into the lobby i was previously in. This is not only extremely irritating for me, but also for all the people i'm playing with as they have to wait until i have logged back in. Its not my computer and because I have asked friends if they have had a similar occurrence and at least 2 says they have but on a less extreme scale. Please fix this as it makes each game less and less enjoyable as i know im going to have to re-log my account at the end.
