"Bad Password" error message when trying to join my friend

Whenever i try to join my friend it just pops up with this error
We last played like 2-3 days ago and we all left in the ancient archives

We disabled all mods, we made a copy of the world, rollbacked, made the server public, removed the password 

Nothing worked we tried basically everything and we asked the people in the discord and they didnt know what was up either

Every other world we host with/without mods or a password doesnt have this error
