Question [Lobby]: Unauthorized, (16401). Message: HTTP/1.1 401 Unauthorized

Hey so I am trying to fix an issue where when the client disconnects, they cant reconnect again to the same lobby, the reason is that the playerID is still registered in the lobby even after leaving, so I used the RemovePlayerAsync in the OnDestroy function as you can see in the script, the issue is when I leave the lobby and try to rejoin, on the client side it throws this error

AuthenticationException: Invalid state for this operation. The player is already signd in

and on the host side this error

[Lobby]: Unauthorized, (16401). Message: HTTP/1.1 401 Unauthorized

and it keeps logging every 5 seconds or so. Weird thing is that if I set the OnDestroy as a command, and I call it while the game is running on the client, it successfully removes the playerID from the lobby (clients doesn't disconnect) and when I leave as the client, I can rejoin the old lobby, but on the host side it starts logging the error again.
I made a video so it's easier to visualize:

Full error:
