Can't join

[Toom_Raider]

I can only join the deathmatch and zombie escape servers. The other servers just first say 'Joining game...' and after a few seconds 'Failed to join game.'
I don't have this problem on any other server.

Deathmatch, Zombie Escape and Multi-1v1 are the only non-steam servers...
