I try to enter a room but I always get a "Server not Responding message". It happens for every game that I try to join. I've checked my internet connection and everything is ok here. And I have even tried joining a room created by my friends.
When I try to find a room through Quick Match, I can't connect either. It just keeps jumping from server to server and I can't connect to any of them:
When I try to create a custom match, I get a "Network Error" message:
I don't know if this is relevant but I own a Macbook, running MAC OS Sierra 10.12.6
Try to join a room through "Browse Servers" or "Quick Match" or try to create a room through "Custom Match".
