"Connection lost Network protocol error"

I can't connect to the server. The error seems to be caused by in-game behavior.

The error happened to me twice. The first time this happened was after I hit a pig. I was simply kicked out of the server and every time I tried to log into the server I was given an error message. This error went away on its own after about 1 day.

The second time this happened was after I opened the chat and entered the command to teleport home (/home 1). This error is still valid and right now I can't log into the server.

P.S. This happened a couple more times when I tried to return to another place of death using the /home command.

P.S.S. Also one time it happened without any reason.
I tried restarting wifi, connecting to another network, turning on VPN, none of this helps.
