You can check for updates by:

Flushing your DNS will clear your PC's DNS cache, and can resolve a variety of connectivity-related issues.
- Run the Command Prompt as an administrator
- Enter the command:
- Restart your PC
Change Your DNS
When clearing the PC's DNS cache has been unsuccessful, we recommend changing the DNS. Instructions on how to switch to Google DNS can be seen here: https://developers.google.com/speed/public-dns/docs/using
Check Your Internet Speeds
Check your connection's download and upload speeds using a website such as https://www.speedtest.net/. An upload speed of less than 1 Mbps is likely to result in an unstable experience, and we recommend not hosting if this is the case.
Disable Background Applications
Background applications can interfere with your connection to our servers.
A Selective Startup can help identify whether a background application is the cause of your errors:
- Press the Windows key
- Type 'msconfig' and select 'System Configuration'

- Deselect 'Load startup Items'
- Reboot your PC
If the issues no longer occur after having performed the Selective Startup, try re-introducing your programs one-by-one to determine which is causing your errors.

Having UPnP enabled in your router will automatically allow the connections needed. If this option is not available to you, please see the 'Port Forwarding' section instead.

- This is usually done through a web browser by navigating to the router’s internal IP address. Consult the router’s user manual for help accessing the control panel
- Find the 'UPnP' option, usually located under the 'LAN' or 'Firewall' category. Consult the router's user manual for help locating the UPnP setting
- Enable UPnP and save the changes
- Disconnect and reconnect all devices on the network
Please only do this if enabling the UPnP option in your router is not an option.

Connect to a Mobile Hotspot
If available, we recommend connecting your PC to a mobile hotspot, to see if the issue persists whilst under another connection.
This can help in isolating the issue to the network or PC.
Switch to a Wired Connection
Vermintide 2 requires a constant and stable internet connection. For the best experience, we strongly recommend a wired internet connection as WiFi connections may lead to issues induced by poor connectivity and stability.
Contact Your ISP
