I just found out that "On Kicked" is being set off which means the peer is being kicked out for some reason.
Triggered if kicked from the current room. This can occur if the host quits, the connection to the host could not be established, or the host otherwise decides to forcibly remove you from the room. After On kicked the player is no longer in the room and must re-join a room to be able to participate in a game."
I think this is whats happening here... So can you just not test multiplayer from the same computer/IP? Is that why its not working?
