Unfortunately, the Connection Timeout error is often router or ISP-related.
To start with, please run through the solutions listed here which may help with your Connection Timeout errors: https://support.fatshark.se/hc/en-us/articles/360021232734--PC-How-to-resolve-Sign-In-Timeout-errors
If unsuccessful, we recommend connecting your PC to a mobile data hotspot (if available), which will allow you to isolate the issue to your connection or to your PC.
If no errors are encountered whilst connected to a mobile data hotspot, then the issue is isolated to your router or ISP. In this situation, we recommend that you reach out to your ISP and explain that you’re having issues with your connectivity to https://5107.playfabapi.com/, which is the endpoint to our backend. Your ISP should be able to see why the connection cannot be established properly.
If the errors persist even whilst connected to a mobile data hotspot, it's likely something on your PC is interfering with your connection to Vermintide 2. Are you using a VPN, proxy or an overzealous Anti-Virus or Firewall program? A Selective Startup may help identify the issue:
- Press the Windows key
- Type 'msconfig' and select 'System Configuration'
- On the 'General' tab, select 'Selective Startup'
- Deselect 'Load startup Items'
- Reboot your PC
If the errors no longer occur after having performed the Selective Startup, try re-introducing your programs one-by-one to determine which is causing your errors.
