It's possible the servers were down at the time of the screenshot to update to v1.2.11
If you haven't already, make sure to download the Taleworlds update.
Then I'm inclined to say something is blocking your connection to the servers. Likely a firewall (local or router/modem) or antivirus.
If your ISP was blocking it, you wouldn't have been able to access this website either.
Alternatively, it can be caused by a VPN or even resolved by using one.
