Multiplayer Starting issues

[Kileratlarge]

I have played many multiplayer games before. Even 20 mins ago it was working. what would happen is when i press internet, it would then starting multiplayer, wait a few seconds, and the other messages, and then it would land on connecting and it wont go any further than that, i have no clue why it isnt working. I was also downloading gsm burning steel 3 in the background but i dont think that affects anything
