The issue: When trying to play Warhammer 40K Inquisitor Martyr (or Prophecy), you get an error about not being able to connect to the servers and have to quit the game.
Possible solutions: If you have Starlink as your internet service provider and are using Windows 11, turn off IPv6 on your network adapter and then try again.
Here's how:
Open Settings: Press Win + I to open Settings, then go to Network & internet > Advanced network settings.
Access Adapter Options: Click on More network adapter options to open the classic Network Connections window.
Properties: Right-click your active Ethernet adapter and select Properties.
Uncheck IPv6: In the list, find and uncheck the box next to Internet Protocol Version 6 (TCP/IPv6).
Confirm: Click OK to save the change.
Now try restarting the game.
Other solutions: From what I can gather, the issue lies with how Starlink does some of its routing and is also tied to DNS (isn't everything?). Others around the net have mentioned using a VPN also solves the issue.
