The DNS_PROBE_FINISHED_NXDOMAIN error appears when your browser cannot find the IP address associated with a domain name. In simple terms, the DNS system is unable to locate the website you are trying to access, preventing the browser from establishing a connection.
This issue can occur on any major browser, including Google Chrome, Microsoft Edge, Mozilla Firefox, and Opera.

What Is the DNS_PROBE_FINISHED_NXDOMAIN Error?
DNS (Domain Name System) translates domain names such as example.com into IP addresses that computers use to communicate with servers.
When the DNS system cannot find a valid record for a domain, the browser displays the DNS_PROBE_FINISHED_NXDOMAIN error. The term NXDOMAIN stands for Non-Existent Domain, indicating that the requested domain name could not be resolved.
Common Causes of the Error
Several factors can trigger this issue:
Incorrect Domain Name
A simple typo in the website address may prevent the browser from finding the correct DNS record.
DNS Configuration Issues
Incorrect DNS settings on your device or network can interfere with domain name resolution.
DNS Server Problems
The DNS servers provided by your internet service provider may be experiencing temporary outages or synchronization issues.
Firewall or Antivirus Restrictions
Security software may block access to certain websites or interfere with DNS requests.
Domain Configuration Errors
If you own the website, the domain may have expired, DNS records may be missing, or the domain may not be correctly connected to the hosting server.
How to Fix DNS_PROBE_FINISHED_NXDOMAIN
1. Verify the Website Address
Carefully check the URL for spelling mistakes or missing characters.
If possible, access the website from your bookmarks or search for it through a search engine.
2. Refresh the DNS Cache
On Windows, open Command Prompt as Administrator and run:
ipconfig /flushdns
This clears locally stored DNS information and forces your system to request fresh records.
3. Restart Your Browser
Close the browser completely and reopen it.
Sometimes temporary browser issues can cause DNS lookup failures.
4. Restart Your Router and Device
Power off your router for approximately 30 seconds and then restart it.
Reboot your computer or mobile device as well.
This can refresh network settings and resolve temporary connectivity issues.
5. Change Your DNS Servers
You can replace your provider’s DNS servers with public DNS services.
Google Public DNS
8.8.8.8
8.8.4.4
Cloudflare DNS
1.1.1.1
1.0.0.1
Using alternative DNS providers often resolves DNS-related issues and may improve browsing performance.
6. Temporarily Disable Security Software
Some antivirus applications and firewalls can block DNS requests.
Temporarily disable them and test whether the website becomes accessible.
If the website loads correctly, review your security software’s settings and exceptions.
7. Check the Domain Status
If the error affects your own website:
- Verify that the domain is active and not expired.
- Confirm that DNS records have been configured correctly.
- Check that nameservers point to the correct hosting provider.
- Ensure DNS changes have fully propagated.
Additional Troubleshooting Steps
Clear Browser DNS Cache (Google Chrome)
Open:
chrome://net-internals/#dns
Click Clear host cache.
Reset Network Settings
On Windows, you can reset network components using:
netsh winsock reset
netsh int ip reset
Restart your computer after running these commands.
Test from Another Network
Try accessing the website using:
- A mobile network
- Another Wi-Fi connection
- A VPN service
This can help determine whether the issue is specific to your internet connection.
Summary
The DNS_PROBE_FINISHED_NXDOMAIN error indicates that a domain name cannot be resolved through DNS. In most cases, the issue can be resolved by checking the domain address, clearing DNS caches, restarting networking equipment, or changing DNS providers.
If the problem affects your own website, verify your domain status, DNS records, and nameserver configuration. Proper DNS setup is essential for ensuring that visitors can reliably access your website.
