DNS_PROBE_FINISHED_NXDOMAIN: The best solutions

Worldwide, roughly two of three users use Chrome to access the internet every day. Google’s web client has become the undisputed number one for many users thanks to regular upgrades and its seamless integration of personal services and settings for other Google services like Drive, Gmail and YouTube. However, the browser isn’t perfect: Chrome suffers from connection problems, bugs and security flaws – just like its well-known alternatives Firefox, Safari and Edge.

For example, Chrome users are not immune to situations in which a visited website is not accessible or available. In cases like that, the browser often outputs the additional error message “DNS_PROBE_FINISHED_NXDOMAIN”. This article tells you what this error means and how you can remedy it.

Of course, as shown in the previous screenshot, the error can be caused if the domain address entered really does not exist because you entered an incorrect address or made a typo. However, the message “DNS_PROBE_FINISHED_NXDOMAIN” is also output in situations when correct name resolution should actually be possible, as the address is a valid domain that exists. In this case, potential sources of error include the following:

• DNS server not working properly
• DNS client not working properly
• Incorrect DNS settings
• Incorrect Chrome settings (especially experimental features)
• Outdated entries in the operating system’s DNS cache
• VPN or antivirus software or a firewall preventing connection

In some operating systems like Windows 10, Chrome gives you a first solution option with the error message: If you click the link displayed, you can start the network diagnostics tool, which initiates an automatic troubleshooting process. Alternatively, clicking the “Reload” button can sometimes be enough to fix the problem.

If the web client outputs the DNS_PROBE_FINISHED_NXDOMAIN message again after reloading or network diagnostics, the following solutions offer the best chances of success.

If you use VPN software to surf and transmit data anonymously and securely via virtual networks, this can be responsible for the DNS_PROBE_FINISHED_NXDOMAIN error. That applies both for external tools as well as VPN extensions you installed in Chrome. The same is true of security software like antivirus programs or firewalls. While these applications are essential to protect your system, they are also known to block connections without a good reason in some situations.

When the name resolution problem occurs, try deactivating this software temporarily. If the site loads after that, you have found the problem and can try to find a solution to stop the tool blocking the site. Alternatively, you can consider changing software.

The DNS cache is closely linked to the above-mentioned DNS client. This temporary storage, which is also created automatically by other operating systems like Linux or macOS, contains entries for web addresses that have been resolved successfully in the past. Browsers use this cache to deliver pages as quickly as possible, but this can cause the DNS_PROBE_FINISHED_NXDOMAIN error if the entries accessed are no longer up-to-date. In this case, the solution is to flush the DNS, deleting the cache contents. Proceed as follows to clear the cache under Windows:

1. Open the Command Prompt.
2. Enter the command “ipconfig /flushdns” and press Enter to confirm.
3. A message tells you that you have successfully deleted the entries.

There can be two reasons your device cannot communicate properly with the DNS server selected or specified by your provider: On one hand, it is possible that the IP addresses entered are not correct or are no longer valid. On the other, the server may be temporarily down. In both cases, Chrome may show the “DNS_PROBE_FINISHED_NXDOMAIN” message to inform you of the problem. Another potential solution is to check the DNS settings or change the DNS server. Users of Windows 10 should proceed as follows:

1. Right-click the Windows logo and select the “Network Connections” item.
2. Click “Change Adapter Options” and then choose the network connection whose DNS server you want to change by right-clicking it.
3. Click “Properties” and then the entry “Internet Protocol Version 4 (TCP/IPv4)”.
4. Check the addresses entered under “Preferred DNS server” and “Alternate DNS server”.
5. Enter the correct IP addresses for the chosen server or the addresses of new servers like the Google DNS server (8.8.8.8 and 8.8.4.4).
