What is the dns_probe_finished_nxdomain Error, and How to Fix It?

When browsing the internet, encountering an error can be frustrating. One common error that users experience is dns_probe_finished_nxdomain. This error prevents you from accessing websites and can disrupt your workflow. However, understanding the root cause and knowing how to fix it can help you resolve the issue quickly. 

In this guide, we’ll explain what the dns_probe_finished_nxdomain error is, why it happens, and effective ways to fix it.

What Does dns_probe_finished_nxdomain Mean?

The dns_probe_finished_nxdomain error indicates that your browser cannot find the IP address associated with the domain name you are trying to access. DNS (Domain Name System) works like a phonebook for the internet. It translates domain names (like www. example .com) into IP addresses that servers use to identify each other. If the DNS cannot resolve the domain name, you receive the dns_probe_finished_nxdomain error. The term "NXDOMAIN" stands for "Non-Existent Domain."

This error typically appears on Google Chrome, but other browsers have similar messages:

Firefox: "Hmm. We’re having trouble finding that site."

Safari: "Safari can’t find the server."

Microsoft Edge: "Hmm, we can’t reach this page."

Common Causes of dns_probe_finished_nxdomain

Several factors can cause the dns_probe_finished_nxdomain error. Understanding these can help you choose the right solution:

Incorrect DNS Settings: If your DNS settings are incorrect, your device won’t be able to resolve domain names.

Network Issues: Problems with your network connection can interrupt DNS resolution.

Browser Cache: Cached data in your browser might cause conflicts.

Outdated DNS Records: Sometimes, the DNS records for a website change, but your system still uses outdated information.

Malware or Viruses: Malware can modify DNS settings and interfere with network connections.

Firewall or Antivirus Software: Overly strict security settings can block DNS queries.

Server-Side Issues: If the website’s hosting server is down, you may encounter this error.

How to Fix dns_probe_finished_nxdomain

Let’s explore practical solutions to resolve this error.

1. Restart Your Router

Sometimes, a simple router restart can resolve DNS errors. To do this:

Turn off your router.

Wait for about 30 seconds.

Turn the router back on and allow it to reboot.

After restarting, try accessing the website again.

2. Clear Browser Cache

Cached data in your browser might be causing the issue. To clear the cache in Google Chrome:

Open Chrome and press Ctrl + Shift + Delete (Windows) or Command + Shift + Delete (Mac).

Select "Clear browsing data."

Check "Cached images and files."

Click "Clear data."

Reload the website and check if the error is resolved.

3. Flush DNS Cache

Flushing the DNS cache can remove outdated DNS records. Here’s how:

On Windows:

Open the Command Prompt (search for "cmd" in the Start menu).

Type: ipconfig /flushdns

Press Enter.

On Mac:

Open Terminal.

Type: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Enter your password and press Enter.

This action clears the DNS cache and refreshes DNS data.

4. Change DNS Servers

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

On Windows:

Go to Settings > Network & Internet > Change adapter options.

Right-click your network connection and select Properties.

Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.

Select "Use the following DNS server addresses."

Enter:

Preferred DNS: 8.8.8.8 (Google DNS)

Alternate DNS: 8.8.4.4

Click OK.

On Mac:

Go to System Preferences > Network.

Select your connection and click Advanced.

Go to the DNS tab.

Click + and add:

8.8.8.8

8.8.4.4

Click OK and then Apply.

5. Disable Antivirus or Firewall Temporarily

Your antivirus or firewall might block DNS requests. Temporarily disable them and check if the website loads. If it does, you might need to adjust the security settings to allow DNS queries.

6. Check the Hosts File

A modified hosts file can block certain websites. To check:

On Windows:

Open Notepad as an Administrator.

Go to File > Open and navigate to C:\Windows\System32\drivers\etc\hosts.

Check if the domain you’re trying to access is listed. If it is, delete the entry.

Save the file.

On Mac:

Open Terminal.

Type sudo nano /etc/hosts and press Enter.

Look for any entries blocking the domain and delete them.

Press Ctrl + O to save and Ctrl + X to exit.

7. Reset Network Settings

Resetting network settings can resolve misconfigurations.

On Windows:

Open Command Prompt as an Administrator.

Run these commands one by one:

netsh winsock reset

netsh int ip reset

Restart your computer.

On Mac:

Go to System Preferences > Network.

Select your connection and click the minus (–) button to remove it.

Click Apply. Re-add the connection and click Apply again.
