Can't join any server at all.

Yeah, basically whenever I try to join a game the message 'connecting to so-and-so server' just stays there.
It flashes once or twice, but after that, nope.
I waited for literally 15 minutes and nothing happened.
I tried this in multiple servers and still got the same result.
Anyone know what's up? Because I can't play Killing Floor.
