Use Google DNS

If a simple restart did not work and you have successfully confirmed that neither Steam nor Fatshark are currently fixing the server problems, you should consider that there may be a Domain Name System (DNS) error.

If you are using layer 2 IPS, you may be assigned an incorrect DNS area, which the game server will reject. If this scenario is applicable, you can solve the problem by switching to Google provided DNS. This fix has been confirmed by several affected users.

  • In the “Network Connections” menu, right-click the network you are currently connected to, then right-click Wi-Fi (wireless connection) depending on how you are connected, or “Ethernet” (network connection) Use, then click Properties in the pop-up menu that appears.
  • On the Network Connection Properties screen, select the “Network” tab, then go to the module. This connection uses the following module, select “Internet Protocol version 4 (TCP / IPv4)” and click on the Properties menu below.
  • When you go to the next menu, select the “General” tab, check the Google checkbox associated with “Use the next DNS server address” and replace the preferred DNS server and the alternative DNS server with the following values:
  • If you can change the values accordingly, repeat steps 3 and 4 again to do the same for Internet Protocol version 6 (TCP / IPv6) for Google DNS:
    • 2001: 4860: 4860 :: 8888
    • 2001: 4860: 4860 :: 8844
  • Save the changes you just made, reboot your computer and see if the problem is solved.
