Correct me if I am misunderstanding anything, but what I do understand is that;
When connecting from the school district, the client goes straight into offline mode. When connecting from home however, the client reaches the server. After the site's crash, no connections are going through.
Just a quick question; Are you trying to connect to the main MPP (
multiplayerpiano.com)?
If that's the case, the main MPP is not yet working at the moment due to maintenance.
