Here is a possible solution for the abandoned connection lost error.

To Reproduce: Sign in and out of your Microsoft account (you dont have to leave the game)

Then you do this again

Lastly whoever is in the server has to invite you and you have to accept the request

(Note: This may only work on Nintendo and PlayStation but feel free to try!)

What Happens:

No Method: Example left the game

With Method: Example joined the game

Note: You may be logged out after you join and you may receive Code Creeper
