Whenever i try and join a room it says

forwarding to ...
Connecting to ...

And says not connected in the middle of the screen.

What server did you try to join?
Did you try to join an official server or a private server?
If you joined an official server, make sure that your belt is right for the server.
If you joined a private server, it might mean that they have set the belt limit higher/lower than your belt.

If you can't join any server, make sure your Firewall isn't blocking Toribash.

Oh thanks, I think I was joining the wrong official server. My belt changed without me noticing it.
