Causes of DNS_PROBE_FINISHED_NXDOMAIN Error
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.
How to Fix DNS_PROBE_FINISHED_NXDOMAIN Error
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Flushing the DNS cache can clear outdated or corrupted DNS records, potentially resolving the NXDOMAIN error.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. - MacOS: Use Terminal and enter
sudo killall -HUP mDNSResponder. - Linux: Use Terminal and enter
sudo systemctl restart network.service.
Method 2: Change DNS Servers
Switching to alternative DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220) 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.
Conclusion
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. Understanding these steps empowers users to resolve issues independently, promoting a seamless online experience without reliance on technical support.
