If the DNS in OpenWRT is unable to resolve, you can try the following troubleshooting methods:

  1. Check network connection: make sure your OpenWRT device is successfully connected to the internet and network configuration is correct.
  2. Check the DNS configuration: Log in to the OpenWRT management interface and verify that the DNS configuration is correct. You can try using other public DNS servers, such as Google’s 8.8.8.8 and 8.8.4.4.
  3. Restart DNS service: Attempt to restart the DNS service on your OpenWRT device by logging in via SSH and executing the following command:
  4. Restart the dnsmasq service by running /etc/init.d/dnsmasq restart.
  5. Clearing DNS cache: Sometimes DNS cache can cause resolution issues. You can try to clear the DNS cache and restart the DNS service by executing the following command:
  6. Restart the dnsmasq service by running /etc/init.d/dnsmasq restart.
  7. Check firewall settings to ensure they are not blocking DNS resolution traffic.

If none of the above methods work, you may need to further diagnose the network connection and DNS configuration, or try resetting the network settings of your OpenWRT device and reconfiguring it. If the issue persists, it is recommended to reach out to a network administrator or the OpenWRT community for further assistance.
