What you need to do to fix the Not Found Session 91 bug
Input the Multiplayer Code again or join another server if there is one available. The Not Found Session 91 error appears if you’re trying to join a non-existent server or session, or if you’ve entered the wrong multiplayer code or the host has shut down the server. You’ll need to look for another session to join, or you’ll need to input the proper multiplayer code to join it.
Make sure that Multiplayer is turned on in the settings
You may encounter this error if the server is confirmed to be up and running, but you still receive the same error message. You might want to double check that the Multiplayer setting is turned on on the server you are trying to join.
If you are using wireless internet, you will need to restart your connection or use wired internet
It is recommended that you switch to a wired connection if you are currently connected to the Internet using WiFi. If you are already connected to the Internet via a wired connection, it is recommended that you restart your modem or router. It is also possible that you are having problems with your connectivity if you have already turned on the server’s Multiplayer Setting and you still receive the error.
