The reason is for the server to understand that you are no longer connected. After this process, start the launcher and log back into your account. The message should disappear afterward.

Fix #3: Reset Your Password

Another reason you may receive this error is if your password has been compromised and someone else is using it, which can result in a double login. 

As soon as the person launches the Minecraft launcher, the server automatically creates a new session ID for you, and the one you are using before becomes an old session. 

The person who logs in after you will play the game, but you cannot. And the session on your own server has become invalid.

To fix this, we would recommend you to change your password to prevent other instances of logins through the same account, just to be certain.

Mod files [1], if corrupt, can make connecting to the server difficult. The solution is to delete all game mods from the game’s directory. This will do a clean uninstall.
