How to Fix the DNS_PROBE_FINISHED_NXDOMAIN Error: A Complete Guide

DNS_PROBE_FINISHED_NXDOMAIN is a common error that prevents users from accessing websites. It occurs when the Domain Name System (DNS) fails to resolve the domain name, meaning your browser can’t find the website you’re trying to visit.

If you’ve encountered this issue, don’t worry. This guide provides step-by-step troubleshooting for Windows, Mac, Android, and Chrome users.

1. What is the DNS_PROBE_FINISHED_NXDOMAIN Error?

When you enter a URL (e.g., www.google.com) in your browser, your device contacts a DNS server to translate the domain name into an IP address. If the DNS lookup fails, you get the DNS_PROBE_FINISHED_NXDOMAIN error, meaning the domain name does not exist.

This issue can be caused by incorrect DNS settings, misconfigured network configurations, or browser issues.

2. Common Causes of the Error

Several factors can lead to the DNS_PROBE_FINISHED_NXDOMAIN error:

✅ Incorrect DNS Configuration – Your device’s DNS settings may be misconfigured.
✅ Network Issues – Problems with your router or internet connection.
✅ Expired or Incorrect Domain Name – If the domain name has expired, the DNS won’t resolve it.
✅ Browser Cache and Cookies – Corrupt cache files can interfere with domain resolution.
✅ VPN or Proxy Interference – Certain VPN or proxy settings may block DNS resolution.
✅ Firewall or Antivirus Blocking Access – Security software may prevent access to certain websites.

3. Quick Fixes

1. Restart Your Router and Computer

• Power off your router and wait 30 seconds.
• Turn it back on and restart your computer.
• Try accessing the website again.

2. Check the URL for Errors

Make sure you typed the correct website address. Typos in the URL can lead to the error.

3. Disable VPN or Proxy Settings

If you’re using a VPN or proxy, disable it temporarily to check if it’s causing the issue.

4. Try a Different Browser

Switch to another browser (e.g., Chrome to Firefox) to check if the problem is browser-specific.

4. Advanced Troubleshooting

If the quick fixes don’t work, try these advanced troubleshooting steps:

1. Flush the DNS Cache

Clearing the DNS cache forces your device to fetch fresh DNS records.

For Windows:

1. Open Command Prompt as Administrator.

2. Restart the DNS Client Service (Windows)

1. Open Run (Press Windows + R).
2. Type services.msc and press Enter.
3. Find DNS Client, right-click, and select Restart.

3. Change Your DNS Server

Switching to public DNS servers like Google DNS or Cloudflare can resolve the issue.

For Windows & Mac:

1. Open Network Settings.
2. Locate your current network connection.
3. Change the DNS servers to:

   Google DNS: 8.8.8.8, 8.8.4.4
   Cloudflare DNS: 1.1.1.1, 1.0.0.1
   

4. Save changes and restart your internet connection.

4. Reset Network Settings

Resetting TCP/IP and Winsock settings can fix connectivity issues.

   ipconfig /release
   ipconfig /renew
   

3. Restart your PC and check your internet connection.
