Sitting in the same house and can not play together

[tankster26]

My son and I have different Game Pass accounts.  We create a server name and try to play together and nothing shows up.  We called Microsoft and they tried to get us to invite each other and then start the game.  He invited me (we are friends on Xbox) and I accepted.  He started his game and I went in to join a game and could not find him.  No matter what we try we can not create or find a server so we can play together.

Have you tried joining via right clicking one another and joining him that way? It works like Steam, you right click and it'll have a Join Game option. Now are you creating a dedicated server or just hitting New Game and hosting it as a peer to peer session? You may also want to try using port 27015, that one always works for me on lan discovery.
