Disconnected:You are already connected

Disconnected:You are already connected.Help me pls.

If it continues, then the server need a restart as it think you’re still on the server.

Had this happening once on my own server, the player was listed as online, but I couldn’t kick him off so was only able to get him removed by restarting server.
I dunno if the server auto sort itself after a longer period of time.

press F1 and type “KILL” then you will be able to connect! someone should stick this answer for everyone that have this problem
