Option 1 : Sign In Manually After Few Minutes

When checking the server status, if all you see is just “Unstable Server “, wait for few minutes and try signing in to the server again periodically. In any chance when someone logs out, you can get into their slot. If it doesn’t work try the below trick.

They have already issued Perma ban to many users and some seemed to be flagged for deletion.
