Router is Asus RT-N66U with latest DD-WRT firmware (v3.0-r33492). Operating system is fully updated Windows 8.1. I have 100Mbps cable connection and every other game is working fine. I haven't found any way to contact Steam support, since all contact forms say that I need to contact Activision support. Yesterday I contacted Activision support and they said that these error messages and behaviour suggest that there is something wrong between Steam and Activision servers (or my Steam account) and then they said that I should contact Steam support about this. I also tried to move my computer to DMZ and disable workstation firewall to make sure neither of those affect this, but no dice. I have port forwarding configured correctly on router and also uPnP is enabled and like I said, everything was working until this situation started out of the blue 3 days ago. System info does not show anything on NAT type anymore, but country is recognized correctly. Looks like the game does not even try to connect anywhere, or there is no response.
Game still starts just fine, but when I click 'Play' on initial menu, it stucks to 'Connecting online services' ( ) and after few minutes it throws an error 103294 or 102526 ( ).
Before this the game was working just fine and NAT type was 'open' in system info within game. Call of Duty: Modern Warfare 2 and Warzone evolve with the franchise. I haven't been able to play COD:WW2 for 3 days now (PC).
