So I decided I wanted to play some Toribash and grind some tc but as soon as I tried to join a session I get 'not connected' even though at the bottom left it says connected then the server ip and port. Any help would be great.

Check if the password in you ingame login is the same as on forums

Also, try re-entering your account on the login tab in-game.

If this fails, ask a member of the Help Squad.

As a simple solution, try whether your firewall is blocking anything related to toribash (do basically toribash and/or steam).
Happens from time to time that it blocks it, just unblock it and see if it works.
