i think the main problem is in link ports and i also has the same (unable to join the game session problem) so i tried to change the ports but in the verification they fail but i tried to join a game it gives me the same message then i returned the ports again to 3071-3072 after that i could join game easily but its just a temporary solution cause the message returned again so i made the same steps again and it works
sorry for my bad english
and anyone has a solution plz write it down
