It always does, without fail, for every pub server, even one I make. What's causing this? I want to play multiplayer man!

Can you be a little more specific?
Do you get an error message in the chat?

But you can try to check whether your firewall is blocking toribash.

Are you using an updated version? (What version are u running?)

Is it your password? Try logging in and back out on the forums to see if it's your password that had to be reset due to you not changing your password in a while.

Try deleting tb_login.dat in the Toribash folder and launching the game again.
