If you're having trouble connecting, try the "UDP Mode" option. We've been having sporadic connectivity problems, usually for just a few minutes at a time, which is making it hard for the ISP to figure out what's going on. They're working on it though.

Yes, okay, to be clear, when I try in TCP mode I see the message "Connected. Sending login request." and then nothing. You're right that UDP mode does connect and I get to the login screen. I guess this is just and FYI that the issues for TCP are still there.
