I've also been getting this error and can't figure out why. I usually stick to playing on a couple of servers regularly, and some days I can connect, other days it just says connecting failed on all of them. Nothing has changed in the time between playing, and the game doesn't tell me anything other than "connecting failed". I've verified my game files, I've tried deleting my settings and profile information, I've tried waiting several hours for the servers to restart. Nothing.
Is there any way I can see exactly why my connection is getting rejected?
Edit: Managed to join a server is Australia... where my ping is about 250-300, which is barely playable. (I'm east coast Canada)
