This is a guide to fixing multiplayer and not being able to join a session in Grounded 2. Learn how to fix joining sessions when the AuthenticateLocalUser Failed 6:36 multiplayer error is encountered..
List of Contents

While the error does say that the problem is an authentication error, the cause may also be just a password input error. Joining a session with the wrong password can display the AuthenticateLocalUser Failed 6:36.
An alternative fix is to have the host restart the game. This error can also show up due to other connection issues, which most can be resolved by the world's host restarting and relaunching the game.
However, this is a temporary fix as the game is still prone to this error even after a restart.
