PC No Connection to matchmaking services possible solution

System: PC and GOG.

Starting with the last update v2.54 I could no longer connect to the matchmaking service so multiplayer was completely gone. I reported the issue to HG and GOG.

However, a Norton Data Protector notice had been popping up so I checked the history.

This appears to be an Antivirus software issue, not NMS.

If you are running Antivirus and can’t connect to the matchmaking service it might be as simple as making NMS.exe an exception to your Antivirus/Data Protection software rules.

In Norton 360 it is simply clicking the “Trust Now” option.

I have sent HG all this information.


That’s why I couldn’t see you in game. I saw you online on GOG, but not in nms.


Yes @gunnar it was really weird going in the Anomaly and there was no one there. :scream:
