If you’ve faced the “dns_probe_finished_nxdomain” error while browsing, you’re not alone. This frustrating issue occurs when your browser fails to resolve the domain name of the website you are trying to access. But don’t worry—this article dives deep into what this error means, common causes, and step-by-step fixes.

) or Cloudflare (1.1.1.1
).When your browser cannot find the IP address that the domain you’re trying to reach maps to, you’ll get the error ‘dns_probe_finished_nxdomain’. DNS works like a phone book to translate plain english domain names (example.com) to computers friendly IP addresses.
But when this process fails, your browser is unable to find the website and will show you the ‘NXDOMAIN’ (no such domain) error.
Several factors can trigger this error:
Misconfigured DNS Settings
In addition, DNS servers with incorrect addresses cannot be resolved properly.
Browser Cache Issues
Local DNS lookups may be interfered by corrupted or outdated browser cache.
Network Problems
The error can appear due to temporary glitches in your internet connection or router.
VPN or Proxy Issues
DNS requests may be blocked by proxies or VPNs or they may simply be operated through the use of non-functional DNS servers.
Domain Configuration Errors
If you’re a domain owner, something is wrong with your DNS records or your domain is about to expire, you can get this error.
This error happens most often because your DNS (Domain Name System) cannot resolve the domain name into an IP address. For normal users who are website visitors and domain owners, we provide some solutions.
The cached data in your browser can sometimes conflict with DNS resolution, causing the NXDOMAIN error. To resolve this, you should clear your browser’s cache and cookies.
In Chrome, navigate to Settings, then Privacy and Security, and look for Clear Browsing Data. Select both “Cached images and files” and “Cookies,” then click “Clear Data” to remove any potentially problematic cached information.
A problem with your network hardware may be temporary. Unplug your router modem for a few minutes and plug it back in again.
Switching to a more reliable DNS server often solves DNS resolution problems. Your internet service provider’s default DNS servers might experience downtime or performance issues. Google Public DNS, Cloudflare, and OpenDNS offer more stable alternatives that can improve both reliability and browsing speed.

Over time, your operating system stores DNS information to speed up future lookups, but this cached data can become outdated or corrupted. Flushing the DNS cache removes these stored entries and forces your system to perform fresh DNS lookups.

You’re absolutely right; there was redundancy in the previous sections regarding the use of DNS verification tools, particularly the Google DIG Tool. I’ve consolidated the information to make it more cohesive and readable.
If you’re a domain owner that’s getting the dns_probe_finished_nxdomain
error, that’s likely because of errors in your domain’s DNS settings. Here’s how you can troubleshoot and resolve the issue:
One fastest way to ensure your domain resolves correctly is to ensure your DNS records are correct. In order for the browser to open the page successfully, the domain has to resolve to an IP address, that is, either an A
record for IPv4, or an AAAA
record for IPv6.
Use DNS Verification Tools:
Steps to Use the Google Dig Tool:

). Double-check for typos to ensure accuracy.Note:
A
records andAAAA
records are necessary for the browser to reach the website.
What to Look For:
NXDOMAIN
response points to potential misconfigurations.Action Steps:
An expired domain won’t resolve in DNS lookups, leading to NXDOMAIN errors.
To verify your domain’s status, perform a WHOIS Lookup to view its expiration date and current registration status. This search will reveal whether your domain remains active or has been suspended or expired. Even if your domain appears active, consider renewing it immediately through your registrar to prevent any potential expiration issues. Additionally, update your contact and billing information to ensure you receive timely renewal notifications and avoid future registration lapses that could cause service interruptions.
DNS changes don’t take effect instantly across the internet. After modifying DNS settings, propagation typically takes anywhere from a few minutes to 48 hours to spread globally across all DNS servers. During this period, some users may continue to experience the NXDOMAIN error while others can access your site normally, depending on which DNS servers they’re using and whether those servers have updated their records.
To monitor propagation status across different geographic regions, use tools like DNS Checker . This service allows you to track where your updated DNS records have taken effect and which regions are still working with cached data. Understanding the propagation process helps manage expectations during DNS changes and prevents unnecessary troubleshooting when the issue is simply a matter of waiting for updates to spread through the global DNS system.
Sometimes the problem originates not with your DNS settings but with the domain registrar.
Contact your registrar’s support team to confirm that your domain is properly configured in their system. Ask them to verify that there are no holds, suspensions, or restrictions applied to your domain that might prevent it from resolving correctly. Registrar-side issues might include payment problems, verification failures, or administrative holds that aren’t immediately visible to you as the domain owner but can cause DNS resolution failures for your website visitors.
If you’re using custom nameservers, they must be properly setup.
Verify that your Pinggy tunnel is active and running.view all active tunnels on the Pinggy Dashboard.
If the tunnel stops or becomes disabled, the public URL will no longer be accessible, resulting in a DNS error.
Solution: Restart the Pinggy tunnel with the same command if needed.
https://rnuma-14-139-241-203.a.free.pinggy.link
).Solution: When you start the tunnel with Pinggy, copy the public URL displayed, save it, and use it to access your server. You can also use the QR code of the URL if provided for quick access.
Solution: If you suspect network issues, restart your modem/router or try connecting via a different network for troubleshooting.
The “dns_probe_finished_nxdomain” error is annoying, but it’s usually something that’s simple to fix. If you follow this guide’s steps, you will get back online rather quickly and quickly get rid of this problem. Some of these solutions will get you the error order, whatever may be the reason, clearing your cache, changing your DNS servers or even troubleshooting your network. Have you seen this error?
