It says "The server is down. Try again in 1 minute." I've tried it a few times now over the last hour and it appears to be down still.

Sometimes it takes a bit longer for the server to start up (it’s necessary to keep trying to log in). Unfortunately, I’m using a free plan for the server, so I can’t control this, as the operating costs wouldn’t be covered since the game is free. The server is online now, so if you're around, give it a try.
