How to Fix Dns_probe_finished_nxdomain

Encountering the error message DNS_PROBE_FINISHED_NXDOMAIN can be frustrating when browsing the internet. This error typically indicates that the DNS (Domain Name System) server is unable to resolve the website's domain name into an IP address, preventing access to the site. Fortunately, there are several effective methods to troubleshoot and fix this issue, ensuring a smoother browsing experience. In this article, we'll explore practical solutions to resolve DNS_PROBE_FINISHED_NXDOMAIN and get you back online quickly.

How to Fix Dns_probe_finished_nxdomain

1. Restart Your Router and Device

Sometimes, the simplest solutions are the most effective. Restarting your router and device can resolve temporary network glitches that cause DNS errors.

• Turn off your router and modem, wait for about 30 seconds, then turn them back on.
• Restart your computer, laptop, or mobile device.
• Reconnect to your Wi-Fi network and check if the problem persists.

This process refreshes your network connection and can often resolve DNS-related issues without further intervention.

2. Clear Your Browser Cache and Cookies

Corrupted cache or cookies can sometimes interfere with DNS resolution. Clearing them can resolve the issue.

• Open your browser settings (for Chrome, go to Settings > Privacy and security).
• Select Clear browsing data.
• Choose the time range to clear (e.g., All time).
• Check the boxes for Cookies and other site data and Cached images and files.
• Click Clear data.

After clearing, restart your browser and try accessing the website again.

3. Change DNS Server Settings

Replacing your default DNS server with a public DNS service can often resolve resolution issues associated with NXDOMAIN.

• Using Google DNS:
• Primary DNS: 8.8.8.8
• Secondary DNS: 8.8.4.4
• Using Cloudflare DNS:
• Primary DNS: 1.1.1.1
• Secondary DNS: 1.0.0.1

To change DNS settings on Windows:

1. Go to Control Panel > Network and Internet > Network and Sharing Center.
2. Click on your active network connection.
3. Select Properties.
4. Double-click on Internet Protocol Version 4 (TCP/IPv4).
5. Select Use the following DNS server addresses.
6. Enter the preferred and alternate DNS addresses (e.g., 8.8.8.8 and 8.8.4.4).
7. Click OK to save changes.

On Mac, navigate to System Preferences > Network > Advanced > DNS to update DNS servers.

4. Flush DNS Cache

Flushing the DNS cache can resolve outdated or corrupted DNS records stored on your device.

For Windows:

• Open Command Prompt as administrator.
• Type: ipconfig /flushdns and press Enter.
• You should see a confirmation that the DNS Resolver Cache was successfully flushed.

For Mac:

• Open Terminal.
• Type: sudo killall -HUP mDNSResponder and press Enter.
• Enter your admin password when prompted.

After flushing, restart your browser and test the website again.

5. Disable VPN and Firewall Temporarily

VPNs and firewalls can sometimes block DNS requests, leading to resolution errors.

• Temporarily disable your VPN service and check if the website loads correctly.
• Disable your firewall temporarily to see if it’s causing the issue.
• If the site loads after disabling, reconfigure your firewall or VPN settings to allow DNS traffic.

Remember to re-enable your security measures once testing is complete.

6. Reset Network Settings

If none of the above solutions work, resetting your network settings can resolve underlying configuration issues.

• On Windows:
1. Open Command Prompt as administrator.
2. Enter the following commands one by one:
   • netsh winsock reset
   • netsh int ip reset
   • ipconfig /release
   • ipconfig /renew
   • ipconfig /flushdns
• On Mac:
1. Go to System Preferences > Network.
2. Select your network connection and click Minus to remove it.
3. Re-add the connection and reconfigure DNS settings if needed.

Restart your device after performing these resets and check if the error persists.

7. Check for Browser or System Updates

Outdated browsers or operating systems can sometimes cause DNS errors. Ensure your system and browser are up to date.

• Update your browser to the latest version.
• Update your operating system with the latest patches and updates.
• Restart your device after updates and test the website again.

8. Contact Your Internet Service Provider (ISP)

If all else fails, the issue might be with your ISP's DNS servers or network configuration. Contact your ISP for assistance or to report the problem. They may have specific instructions or outages affecting DNS resolution.
