I cant go into ANY room at all, I restarted my computer, whats the problem?

It might be this, it's happened to me though, just wait a few minutes, occasionally either tb or the servers kinda wierd-out and the servers just dont show up, it's happened to me. Other than that, idk Џ\(А_o)/Џ

Check your firewall exception list. Add Toribash to exceptions so that it's allowed to use the internet properly.

What rooms are you trying to enter?
You might want to check this out.

Also if it gives you the whole server list and you can log in then you're just trying to enter the wrong servers since if your connection's bad then you wont be able to see or do any of those.

This is happening to me, too.
I've played it fine this morning, but now even after waiting 4 hours I can't connect to any multiplayer games.

Are you sure that you are no trying to connect to Beginner servers?

You won't be able to connect to those.
