Game kicks me out sometimes when a match loads

I've been having the exact same problem for about three days now. At first, I thought it was a problem with a changed DNS server (I did this because of problems with another game), but when I set "Automatic DNS," it started loading into a couple of games and then kicking me out. I haven't found a solution yet, but it's annoying sometimes, especially when it comes to loading the game, the intro, and finding a match.
