Can't connect to any games, have latest patch

[Tactrohs]

Yeah, like the thread title says. When I try to join the games shown in teal, it says 'connecting' for 2-3 minutes, then 'connection failed'. The two servers are both 'unavailable' to me and when I host a game I get the message that I may be behind a firewall. I am on a LAN with a firewall, and no option to change the settings, but it has never caused me any problems with any other games.

EDIT: nvm, it turns out the cause of the problems was that I connected to the network after starting up the game. I restarted the game and it's working fine now.
