I have been completely unable to play Dawn of War III for two weeks now. Initially it was because I was using a beta version of Steam, which caused the game to crash. However now it's because I cannot connect to the relic servers from anywhere. I have tried tethering to my phone with no luck, I have eliminated other network issues on my home network by isolating my machine as the only connected device with a raw mapping direct to the WAN address - still no luck. I have tried on two separate Windows 10 PC's.
I can see in TCP view that the client connects to an IP address over port 443, however the game still refuses to connect and I get the error "Relic servers currently unavailable. Error -4"
Any assistance would be appreciated.
