Can you verify that https://5107.playfabapi.com works? I.e. a blank page with working encryption?

Should be a certificate like this:

Have you recently made any changes to your computer’s hosts? (C:\Windows\System32\drivers\etc)

I ask as changes to the hosts can result in this error for players that aren’t based in Russia or Turkey.

If not, I’d recommend that you scan your PC for viruses and malware.

Are you using a VPN or anything else that could be interfering with your connection?

Try running a Selective Startup on the problematic PC and see if the issue persists:

1. Press the Windows key
2. Type ‘msconfig’ and select ‘System Configuration’
3. On the ‘General’ tab, select ‘Selective Startup’
4. Deselect ‘Load startup Items’
5. Reboot your PC
6. Launch Vermintide 2 as normal

I think, in this case, you should contact your ISP and explain your issues connecting to https://5107.playfabapi.com/ (the endpoint to our backend). Hopefully, they can see where the connection is breaking.
