When I try to join a Minecraft server it says invalid session?
1 Answer. Just as the error says your session ID, what you log in with, is invalid. This usually happens when you log in to your account and then have a new instance of minecraft and log in again without closing down the old one. The old session ID is invalidated as soon as the new connection is made.
