DNS_PROBE_FINISHED_NXDOMAIN is a common error encountered by internet users, indicating that the DNS server could not resolve the domain name. This error can be frustrating as it prevents users from accessing certain websites or services. Understanding the root causes and solutions to this issue can help resolve it effectively, ensuring a seamless browsing experience without disruptions caused by DNS resolution errors.


Several factors can lead to the DNS_PROBE_FINISHED_NXDOMAIN error:

1. DNS Configuration Issues

Incorrect DNS settings or misconfigured DNS servers can trigger this error. Ensure your DNS settings are correctly configured either manually or automatically assigned by your ISP.

2. Website Domain Issues

If the domain itself is not registered or has expired, your browser won’t be able to find its IP address, resulting in the NXDOMAIN error. Check the domain’s status using WHOIS tools.

3. Firewall and Security Settings

Sometimes, overly strict firewall settings or antivirus software may block legitimate DNS queries, leading to the NXDOMAIN error. Temporarily disable such software to see if the issue resolves.

4. Router Configuration Problems

Your router’s configuration might interfere with DNS resolution. Resetting your router or updating its firmware can sometimes resolve DNS-related issues.

5. Internet Service Provider (ISP) Issues

Temporary DNS outages or problems at your ISP’s end can also cause the NXDOMAIN error. Contact your ISP for assistance or wait until the issue is resolved.



Method 1: Flush DNS Cache

Flushing the DNS cache can clear outdated or corrupted DNS records, potentially resolving the NXDOMAIN error. Here’s how to do it:

  • Windows: Open Command Prompt and type ipconfig /flushdns.

  • Linux: Use Terminal and enter sudo systemctl restart network.service.

Method 2: Change DNS Servers

Switching to alternative DNS servers like Google DNS ( and or OpenDNS ( and can sometimes bypass DNS-related issues caused by your ISP.

Method 3: Check Hosts File (Advanced Users)

Inspecting the hosts file on your computer can reveal if any entries are overriding DNS resolution. Ensure there are no incorrect entries that could lead to the NXDOMAIN error.

Method 4: Disable VPN and Proxy

VPN connections or proxy servers might interfere with DNS resolution. Temporarily disable them to check if they are causing the NXDOMAIN error.

Method 5: Restart DNS Client Service

Restarting the DNS Client service on your computer can refresh DNS settings and potentially resolve DNS-related errors like NXDOMAIN.

Method 6: Restart Router and Modem

Power cycling your router and modem can sometimes clear temporary glitches affecting DNS resolution.


Resolving the DNS_PROBE_FINISHED_NXDOMAIN error requires systematic troubleshooting of DNS settings, router configurations, and potential software conflicts. By following the methods outlined above, you can effectively diagnose and fix this frustrating error, ensuring smooth and uninterrupted internet browsing.
