4. Disable your antivirus and firewall
Antivirus and firewall solutions are necessary if you want to protect your PC from malicious users, but sometimes your antivirus and firewall can interfere with your Internet connection.
To fix DNS server connection issues on Windows 10, try temporarily disabling your antivirus and firewall client.
Keep in mind that your PC will still be protected by Windows Defender even if you disable your antivirus, so there’s no need to worry about your safety.
If your antivirus or firewall client was causing this issue, be sure to change its configuration or switch to a different client.
Users reported that Bitdefender Total Security can sometimes cause this problem to appear. If you’re using Bitdefender, you need to go to Firewall settings and disable Block Internet connection sharing option.
After that, the problem should be resolved. Users reported that Avast can also cause this problem. To fix it, simply open Avast settings and disable the Secure DNS option.
You can also try disabling the firewall on your router. This is a bit advanced and potentially dangerous solution, so keep that in mind. By disabling your router’s firewall your PC will be completely vulnerable.
If you decide to do that, just disable your router’s firewall temporarily and check if that fixes the problem.
If the problem was your firewall, you need to turn it back on again and check your firewall configuration for the source of the problem.
To see how to disable your router’s firewall be sure to check its instruction manual.
