How to Fix DNS_PROBE_FINISHED_NXDOMAIN Error and Get Back Online

DNS_PROBE_FINISHED_NXDOMAIN means your device couldn't find the website because the domain name doesn't resolve to an IP address. This usually happens due to DNS problems, network issues, or browser glitches. You can fix it by checking the URL, restarting your router, clearing your browser cache, or changing your DNS settings.

What does DNS_PROBE_FINISHED_NXDOMAIN mean and why do I see it?

This error message appears when the Domain Name System (DNS) lookup fails. DNS translates website names into IP addresses that computers use to connect. Seeing DNS_PROBE_FINISHED_NXDOMAIN means your device asked the DNS server for the website's address, but the server responded that the domain does not exist. This can happen if the website address is typed incorrectly, the DNS server has outdated or incorrect information, or the domain itself is offline or no longer active.

Here is the exact error text you might see:

DNS_PROBE_FINISHED_NXDOMAIN

Could this be a problem with my internet connection or device?

Sometimes this error is caused by your own device or network setup rather than the website. To check, try visiting other websites. If other sites load normally, the problem is likely with that specific domain. If no sites load, your internet connection or DNS settings might be the issue. You can also test another device on the same network. If the error appears there too, it usually means there is a problem with your network or DNS configuration rather than just your device or browser.

Before you start

This guide applies to all common operating systems including Windows, macOS, and Linux. You will need administrator or sudo privileges for some steps, like flushing the DNS cache or resetting network settings. Restarting your computer and router is safe and recommended early on. Before making changes, confirm your internet connection is active by trying to access other websites.

How do I fix DNS_PROBE_FINISHED_NXDOMAIN starting with the easiest steps?

1. Double-check the website address for typos.

2. Refresh the browser page to rule out temporary glitches.

3. Clear your browser’s cache and cookies, which can store outdated information.

4. Restart your router and modem by unplugging them for about 30 seconds and plugging them back in.

5. Try opening the site in a different browser or on another device to see if the issue is browser-specific.

What advanced steps should I try if the simple fixes don’t work?

1. Change your DNS servers to reliable public options like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1).

2. Flush your DNS cache to clear stored address data that might be outdated or corrupted.

• On Windows, open Command Prompt as Administrator and run:

ipconfig /flushdns

• On macOS, open Terminal and run:

sudo killall -HUP mDNSResponder

3. Reset your network settings to restore default configurations.

• On Windows, open Command Prompt as Administrator and run:

netsh winsock reset
netsh int ip reset

Then restart your computer.

Changing DNS servers and flushing caches often fix lookup problems caused by your ISP’s DNS or corrupted data.

How can I verify the error is resolved and the site loads correctly?

After applying fixes, reload the website in your browser. If it opens without error, the problem is likely fixed.

For a more technical check, use command-line tools like ping or nslookup:

• Run nslookup example.com to see if your DNS server returns the correct IP address.

If you get a valid IP address, the DNS resolution is working.

Testing the website on another device or network can also confirm the fix. If the error continues on all devices, further troubleshooting or contacting your ISP might be necessary.

How can I prevent DNS_PROBE_FINISHED_NXDOMAIN from happening again?

To reduce the chances of this error recurring:

• Use reliable DNS servers like Google DNS (8.8.8.8, 8.8.4.4) or Cloudflare (1.1.1.1).

• Keep your network drivers and system software updated.

• Avoid unnecessary manual DNS changes, and if you make any, keep a record so you can revert.

• Restart your router occasionally to clear network caches.

• Always double-check website addresses before entering them to avoid typos that cause DNS errors.

Conclusion

If you see DNS_PROBE_FINISHED_NXDOMAIN, start by verifying the URL, refreshing the page, clearing your browser cache, and restarting your router. If those steps don’t work, change your DNS servers and flush your DNS cache. Use tools like nslookup to check if DNS resolution works. Keeping your network settings updated and using reliable DNS servers helps prevent this error. If the problem continues, consider contacting your internet provider or checking the website’s status.
