Hey guys, need some assistance with connection

So my friend bought the game and he hasnt been able to join any server, we tryed literally everything but no success what so ever. He can’t see any server on the browser list and he is also unnable to join via direct IP, Im starting to think this might be hardware related but i have no idea. If any of you guys have ideas or a solution for this i would be really grateful, thanks ppl
