I’m playing on my computer threw Xbox game pass and my friend is playing on his Xbox One X. We got the game together and played the for a few hours together. We didn’t play for a few weeks and now we are trying to play again together and it keeps giving us a “Connection Failed” box with the message “Failed to join the multiplayer session, or the session is full. (0x00000001)” it gives both of us this error whether we try to join each other or try to accept invites.
Both of us are online and can join other people’s open multiplayer games just not each other.
