Servers Don't Work

When I try to start my server (or join another server from a published game) it does not work. When I start the server, the server starts (like it calls the serverInit() function) but does not actually start. Also it says relay server not available, not quite sure what that means but it isn't available.

If anyone has any idea what I can do to fix this, please comment down below. (also please tell me if I've been blocked from using servers)

Just restarted the relay, sorry!

I am still seeing the problem outlined above by @VoiderYT. Should the relay restart have solved all these issues or are they still ongoing?

The problem seems to have started again. Is there anything I am doing wrong when starting the server? or is this not my fault?
