Understanding the DNS_PROBE_FINISHED_NXDOMAIN Error

The DNS_PROBE_FINISHED_NXDOMAIN error occurs when your browser is unable to find the IP address corresponding to the website domain you are trying to visit. This error means the domain name does not exist or cannot be resolved by the DNS server. It often appears as a message like 'This site can’t be reached' or 'Server DNS address could not be found.'

What it means

This error indicates a failure in the Domain Name System (DNS) lookup process. When you enter a website URL, your device queries DNS servers to translate the domain name into an IP address. If the DNS server cannot find the domain or returns a non-existent domain (NXDOMAIN) response, your browser displays this error.

Common causes

Common causes of the DNS_PROBE_FINISHED_NXDOMAIN error include incorrect DNS settings, problems with your internet connection, issues with your router, corrupted DNS cache, or problems on the website’s DNS server side. It can also be caused by firewall or antivirus software blocking DNS requests.

How to fix DNS_PROBE_FINISHED_NXDOMAIN

  1. Check your internet connection to ensure it is active and stable.
  2. Restart your router and modem to refresh network settings.
  3. Clear your browser’s DNS cache by restarting the browser or flushing DNS cache on your device.
  4. Flush the DNS cache on your computer using command prompt or terminal commands (e.g., 'ipconfig /flushdns' on Windows).
  5. Change your DNS server settings to use reliable public DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).
  6. Disable any VPN, proxy, firewall, or antivirus software temporarily to check if they are causing the issue.
  7. Reset your network settings to default to fix any misconfigurations.
  8. Try accessing the website from a different device or network to determine if the issue is device-specific.
  9. Contact your Internet Service Provider (ISP) if the problem persists, as it might be related to their DNS servers.
  10. If you own the website, verify your domain’s DNS records are correctly configured and not expired.

By following these steps, you should be able to resolve the DNS_PROBE_FINISHED_NXDOMAIN error and regain access to your desired websites. If problems continue, consider seeking help from technical support or your ISP to diagnose deeper network issues.
