DNS_PROBE_FINISHED_NXDOMAIN: How to Fix the Error

Have you ever tried opening a website in Chrome only to see “DNS_PROBE_FINISHED_NXDOMAIN”? This error can be frustrating because the website may have worked perfectly a few minutes earlier.

The good news is that a DNS error does not necessarily mean the website or hosting server is down. In many cases, the problem is related to your computer’s DNS cache, network configuration, DNS server, domain settings, or browser.

In this guide, you’ll learn how to fix DNS_PROBE_FINISHED_NXDOMAIN, what the error means, why it happens, and how to troubleshoot it on Windows and Chrome. We’ll also cover how to flush the DNS cache, change your DNS server, use Google DNS or Cloudflare DNS, and identify whether the problem is on your device or with the website itself.

Quick answer: DNS_PROBE_FINISHED_NXDOMAIN means that the DNS lookup could not find the requested domain. Start by checking the domain name, restarting your router, flushing your DNS cache, and testing with another DNS server.

What Is DNS_PROBE_FINISHED_NXDOMAIN?

DNS_PROBE_FINISHED_NXDOMAIN is a browser error that usually appears when Chrome cannot resolve a domain name to its corresponding IP address.

DNS, or Domain Name System, translates human-readable domain names such as example.com into IP addresses that computers use to communicate with servers.

When a DNS resolver receives a request for a domain that does not exist or cannot be properly resolved, it can return an NXDOMAIN response. Google Public DNS, for example, returns NXDOMAIN for domains that do not exist according to DNS protocol standards.

In simple terms:

Website name → DNS lookup → IP address → Website

If the DNS lookup fails, Chrome may display:

DNS_PROBE_FINISHED_NXDOMAIN

This is why the error is also commonly described as a DNS server not found error, DNS resolution error, or DNS lookup failed error.

What Causes the DNS_PROBE_FINISHED_NXDOMAIN Error?

There isn’t just one cause. The problem can originate from your device, network, DNS provider, browser, or the domain itself.

Common causes include:

Google’s DNS troubleshooting documentation also highlights domain delegation, authoritative nameserver availability, DNSSEC configuration, and incorrect nameserver information as possible causes of DNS resolution failures.

How to Fix DNS_PROBE_FINISHED_NXDOMAIN

Try the following solutions in order. You don’t necessarily need to perform every step.

1. Check the Website Address

Before changing any settings, make sure the domain name is correct.

For example:

example.com

is different from:

exampel.com

A simple spelling mistake can cause an NXDOMAIN response because the requested domain does not exist.

Also check whether you’re trying to access the correct subdomain, such as:

www.example.com

instead of:

blog.example.com

2. Restart Your Router

A simple router restart can sometimes resolve a temporary DNS connection error.

Turn off your router, wait approximately 30 seconds, and turn it back on.

After the connection is restored, open Chrome and try the website again.

This can refresh the network connection and allow your device to receive fresh DNS information.

3. Flush the DNS Cache

One of the most effective ways to fix a local DNS cache error is to flush the DNS cache.

Flush DNS Cache on Windows

Open Command Prompt as Administrator and run:

ipconfig /flushdns

You should see a message indicating that the DNS Resolver Cache was successfully flushed.

Then restart Chrome and test the website.

You can also renew your IP configuration:

ipconfig /release

ipconfig /renew

If necessary, restart your computer after completing these commands.

4. Restart the DNS Client

Windows maintains DNS-related services that help resolve domain names.

You can restart the DNS Client service by opening Services and locating:

DNS Client

Restart the service if Windows allows the action.

Then reopen Chrome and check whether the DNS_PROBE_FINISHED_NXDOMAIN error in Chrome has disappeared.

5. Change Your DNS Server

Your internet provider normally supplies DNS servers automatically. However, the resolver provided by your ISP may occasionally experience availability or resolution problems.

Changing DNS providers can help determine whether your current resolver is causing the problem.

Popular options include:

Google officially documents 8.8.8.8 and 8.8.4.4 as its IPv4 Public DNS addresses.

How to Change DNS on Windows

Go to:

Settings → Network & Internet → Your Network → DNS Server Assignment

Choose Edit, select Manual, enable IPv4, and enter your preferred DNS addresses.

For example:

Preferred DNS: 8.8.8.8
Alternate DNS: 8.8.4.4

Save the settings and test the website again.

Important: Keep a record of your original DNS settings before making changes so you can revert them if necessary. Google also recommends recording existing DNS settings before switching to Google Public DNS.

Google DNS vs Cloudflare DNS

Both Google DNS and Cloudflare DNS are popular alternatives when troubleshooting DNS resolution problems.

Changing DNS does not fix every NXDOMAIN problem. If the domain genuinely does not exist or its authoritative DNS configuration is broken, switching resolvers may not solve the underlying issue.

6. Clear Chrome’s DNS Cache

Chrome maintains its own DNS-related cache.

To clear it, enter:

chrome://net-internals/#dns

in the Chrome address bar.

Click:

Clear host cache

Then close and reopen Chrome.

This can help when Chrome continues using outdated DNS information even after your operating system’s DNS cache has been cleared.

7. Disable VPN or Temporarily Check Security Software

VPN applications, firewalls, antivirus software, browser extensions, and security tools can sometimes interfere with DNS requests.

If the problem started immediately after installing or enabling one of these tools, temporarily disable it and test the website.

Do not permanently disable security software just to solve a DNS problem. The goal is to identify whether the software is responsible.

If the website works after disabling the VPN, check the VPN’s DNS settings or contact its support team.

8. Reset Network Settings

If you’ve tried the previous solutions and still receive a Chrome DNS error, resetting your network configuration may help.

On Windows, you can use Command Prompt as Administrator and run:

netsh winsock reset

netsh int ip reset

ipconfig /flushdns

Restart your computer after running these commands.

This resets important networking components and can resolve configuration-related DNS problems.

9. Check Whether the Problem Affects Other Websites

Try opening several unrelated websites.

For example:

• Google
• Microsoft
• Wikipedia
• Another website you regularly use

If only one website produces DNS_PROBE_FINISHED_NXDOMAIN, the issue may be associated with that domain.

If many websites fail to load, your local network or DNS resolver is more likely to be responsible.

This simple test can save considerable troubleshooting time.

10. Test the Website Using Another Network

Try accessing the website through:

• Mobile hotspot
• Another Wi-Fi network
• Another computer
• Another phone

If the website works on mobile data but not your home Wi-Fi, the issue is probably related to your local network, router, ISP DNS, or DNS configuration.

If the website fails everywhere, the problem may be on the domain side.

How Website Owners Can Fix an NXDOMAIN Error

If you’re a website owner and visitors report DNS_PROBE_FINISHED_NXDOMAIN, don’t immediately assume that your hosting server is offline.

First check your domain and DNS configuration.

Verify Your Nameservers

Make sure your domain is using the correct authoritative nameservers.

Incorrect nameservers can prevent DNS resolvers from finding your website’s DNS records.

Check Your A Record

Your domain’s A record should point to the correct server IP address.

For example:

example.com → A → 192.0.2.10

Use your actual hosting server IP rather than the example address above.

Check the WWW Record

If your main domain works but www does not, check whether the www record exists and points to the correct destination.

Check Domain Expiration

An expired domain can stop resolving properly. Verify the domain registration status through your registrar.

Check DNSSEC

Incorrect DNSSEC configuration can cause DNS resolution failures. Google’s domain troubleshooting documentation specifically recommends checking DNSSEC and delegation when diagnosing domain resolution problems.

Check DNS Propagation

If you recently changed nameservers or DNS records, different DNS resolvers may temporarily have different cached information.

Don’t repeatedly change DNS records during propagation. Verify the intended configuration first and allow sufficient time for the changes to update.

DNS Troubleshooting: User Problem vs Website Problem

Use this quick comparison to identify where the problem probably exists.

Google’s DNS troubleshooting tools can help administrators investigate domain resolution, nameserver delegation, DNSSEC, and authoritative-server problems.

How DNS and Web Hosting Work Together

DNS and web hosting are related, but they are not the same thing.

Think of DNS as an internet address book.

Your domain tells visitors which address to use, while hosting provides the server where the website files are stored.

A simplified process looks like this:

Visitor enters domain → DNS finds IP address → Browser connects to server → Hosting delivers website

This is why a DNS problem can prevent access to a perfectly healthy hosting server.

Expert Tips to Prevent Future DNS Problems

A few simple practices can make DNS troubleshooting easier:

1. Keep your domain registration active.
2. Record your DNS and nameserver configuration before making changes.
3. Avoid changing multiple DNS records at the same time unless necessary.
4. Use reliable DNS providers.
5. Monitor important DNS records after migrations.
6. Keep your hosting and domain registrar information organized.
7. Test both the root domain and www version after DNS changes.
8. Use DNS diagnostic tools when troubleshooting persistent problems.
9. Check DNSSEC if your domain uses it.
10. Contact your hosting provider if the domain resolves incorrectly after a migration.

Google Public DNS also provides a DNS lookup interface and troubleshooting documentation that can help identify resolution problems.

Final Thoughts

The DNS_PROBE_FINISHED_NXDOMAIN error can look complicated, but the underlying problem is usually straightforward: your browser cannot obtain a valid DNS answer for the requested domain.

Start with the simple solutions—check the URL, restart your router, flush the DNS cache, clear Chrome’s DNS cache, and try another DNS server. If the issue affects only one domain, investigate the domain’s nameservers, DNS records, expiration status, and DNSSEC configuration.

For website owners, reliable hosting and proper DNS configuration go hand in hand. VeeroTech provides hosting solutions ranging from affordable shared hosting to managed WordPress, semi-dedicated, and managed VPS hosting.

Frequently Asked Questions

1. What does DNS_PROBE_FINISHED_NXDOMAIN mean?

DNS_PROBE_FINISHED_NXDOMAIN means the DNS lookup for a requested domain returned an NXDOMAIN result, indicating that the domain or hostname could not be found by the resolver.

2. How do I fix DNS_PROBE_FINISHED_NXDOMAIN in Chrome?

Start by checking the URL, restarting your router, flushing your DNS cache, clearing Chrome’s host cache, and trying another DNS server such as Google DNS or Cloudflare DNS.

3. Can flushing DNS fix the NXDOMAIN error?

Yes. If outdated or incorrect DNS information is cached locally, flushing the DNS cache can resolve the problem. However, flushing DNS won’t fix an incorrectly configured or expired domain.

4. Is DNS_PROBE_FINISHED_NXDOMAIN a hosting problem?

Not necessarily. The error usually relates to DNS resolution. A website’s hosting server can be operating normally while the domain’s DNS records, nameservers, or local resolver are preventing visitors from reaching it.

5. Should I use Google DNS or Cloudflare DNS?

Both are popular public DNS resolvers. Google Public DNS uses 8.8.8.8 and 8.8.4.4, while Cloudflare provides 1.1.1.1 and 1.0.0.1. Changing DNS can help diagnose resolver-related issues, but it won’t correct problems with the domain’s authoritative DNS configuration.
