DNS_PROBE_FINISHED_NXDOMAIN: causes and fixes

Key takeaways

DNS_PROBE_FINISHED_NXDOMAIN means the browser cannot find the domain’s IP.
The error usually comes from local DNS, browser, network, or domain issues.
Common fixes include restarting your device, flushing DNS, changing DNS servers, and checking VPN or antivirus settings.
If you own the site, check your nameservers, DNS records, domain status, and recent DNS changes.

The DNS_PROBE_FINISHED_NXDOMAIN error appears when your browser cannot resolve a domain name to an IP address. In plain terms, the browser asked DNS where the site lives, and DNS came back with no valid answer.

That can happen because of a local DNS problem on your device, a browser or network issue, or a domain setup problem on the website side. The result is the same either way: the site does not load.

What DNS_PROBE_FINISHED_ NXDOMAIN means

NXDOMAIN stands for non-existent domain. When DNS cannot find the requested domain or return a valid IP address for it, the browser shows this error instead of loading the website.

DNS usually acts like an internet directory. It connects human-readable domain names to the IP addresses browsers need in order to reach a site. When that lookup fails, visitors cannot access the page, and site owners risk lost traffic and trust.

What causes DNS probe failure

Several different issues can trigger this error. Some are local and easy to fix. Others point to a problem with the domain or DNS setup.

Mistyped or incorrect URL. A typo is one of the simplest causes. If the domain is wrong, DNS cannot resolve it.
Local DNS cache issues. Your device stores DNS data locally to speed up lookups. If that cached information is outdated or incorrect, the browser may keep trying the wrong result.
Incorrect DNS server settings. If your computer or router uses a DNS server that is slow, misconfigured, or unavailable, lookups may fail. Switching to a public DNS provider often resolves this.
VPN, proxy, antivirus, or firewall interference. VPNs, proxies, antivirus tools, and some security settings can interfere with DNS resolution or block certain requests.
Domain or DNS misconfiguration. If you own the site, wrong nameservers, missing DNS records, expired domains, or incomplete DNS changes can all produce NXDOMAIN results.
Temporary browser or network problems. A browser issue, stale browser DNS cache, or a temporary network problem can also trigger the error.

How to fix DNS_PROBE_FINISHED_ NXDOMAIN

Work through these fixes in order. Start with the simplest checks first.

1. Check the URL for typos

Make sure the domain is spelled correctly. Confirm the extension too, especially if the site uses .com, .net, .org, or a country-specific domain.

2. Restart your browser, computer, and router

A basic restart can clear temporary DNS or network issues.

3. Clear browser cache and cookies

Browser cache and cookies can sometimes create conflicts. Clearing them is a fast way to rule out stale local data.

4. Flush the DNS cache

Flushing DNS forces your device to request fresh DNS information instead of relying on old cached data.

On Windows, open Command Prompt as an administrator and run:

On macOS, open Terminal and run:

On Linux, the command depends on the service in use, but restarting the resolver service is a common first step.

5. Release and renew your IP address

If the issue is tied to your local network configuration, renewing your IP address can help reset connectivity.

On Windows, run:

6. Change your DNS servers

Try switching to a public DNS provider such as:

Google DNS: 8.8.8.8 and 8.8.4.4
Cloudflare DNS: 1.1.1.1

This is one of the most common fixes across troubleshooting guides because it rules out problems with your current DNS provider.

7. Clear the Chrome DNS cache

If the error appears in Chrome, clear Chrome’s own DNS cache.

Type chrome://net-internals/#dns in the address bar.
Click Clear host cache.

8. Reset Chrome flags

Experimental Chrome flags can interfere with DNS resolution. If you changed them, reset them.

Type chrome://flags
Click Reset all
Restart Chrome.

9. Disable VPN, proxy, or antivirus temporarily

Turn these off briefly to test whether one of them is blocking DNS requests. If the site starts loading, you have narrowed the issue to a local security or routing setting.

10. Check the local hosts file

A bad entry in your hosts file can override normal DNS resolution and point the domain incorrectly or block it entirely. Review the file and remove any outdated entries for the affected domain.

Visitor-side vs. site-owner causes

This error means different things depending on who you are.

If you are trying to visit a site

The problem is often local. Focus on:

browser cache
local DNS cache
DNS server settings
VPN or antivirus interference
router or network issues

If you own the website

The problem may be on the domain or DNS side. Focus on:

nameservers
A and CNAME records
domain status
recent DNS changes
DNS propagation

How to tell which side the problem is on

Test the site on another device, another browser, or another network. If the error only appears in one place, the issue is probably local. If it appears everywhere, the problem may be with the domain or DNS configuration.

How to fix sites that can’t be reached

If a site cannot be reached and you are not sure whether NXDOMAIN is the real problem, use these checks first:

Test another browser or device. If the site works elsewhere, start with the affected browser or machine.
Test another network. Switch from Wi-Fi to mobile data, or try another internet connection. This helps identify local network DNS issues.
Use a DNS lookup tool. A DNS checker or command such as nslookup can show whether the domain resolves publicly or whether the failure is limited to your environment.
Check whether one site fails or many. If many unrelated sites fail, your DNS provider or local network is a stronger suspect. If only one site fails, the domain itself may be the issue.

DNS checks for site owners

If you manage the website, move beyond browser fixes and check the domain setup itself.

Check nameservers. Make sure the domain points to the correct nameservers. Wrong nameservers can stop the domain from resolving at all.
Check DNS records. Review the A record, CNAME records, and any recent DNS edits. A missing or incorrect record can trigger NXDOMAIN responses.
Check domain expiration and status. Expired domains or domains in the wrong registrar status can stop resolving properly.
Check DNS propagation. If you recently changed nameservers or records, allow time for propagation. Some changes appear quickly, but full propagation can still take up to 24 to 48 hours.
Confirm settings with your registrar or host. Check the domain control panel and hosting dashboard before making more changes. Many DNS issues come from simple mismatches between where the domain points and where the site actually lives.

Browser and operating system fixes

Different browsers surface this error in different ways, but the troubleshooting path stays similar.

Window fixes

Windows users should focus on:

flushing DNS with ipconfig /flushdns
renewing the IP address
restarting the DNS Client service
checking adapter DNS settings

macOS fixes

macOS users should focus on:

flushing the DNS cache
reviewing DNS server entries in Network settings
renewing the network connection
restarting the local resolver service

Linux fixes

Linux users should focus on:

reviewing resolver settings
updating DNS server entries
restarting the local resolver or network service
checking for local hosts file overrides

Chrome-specific fixes

Chrome users can clear the browser DNS cache and reset Chrome flags if standard steps do not help.

Other browser checks

Firefox and Edge also provide DNS cache clearing options. Safari users usually handle this through macOS network settings and DNS configuration.

How to prevent DNS_PROBE_FINISHED_ NXDOMAIN from happening again

A one-time fix is helpful. Preventing repeat issues is better.

Keep DNS records accurate. Review nameservers and DNS records carefully before and after making changes.
Use reliable DNS servers. Public DNS providers or well-managed DNS services can reduce lookup problems caused by poor resolver performance.
Track domain renewals. Do not let the domain expire. That is one of the simplest ways to end up with avoidable DNS problems.
Avoid unnecessary local overrides. Old hosts file entries, browser experiments, and local DNS tweaks can create problems later.
Monitor uptime and DNS health. If the site matters to your business, proactive monitoring matters too.

When to stop troubleshooting and contact support

There is a point where more local troubleshooting stops being useful.

Contact support when the issue is likely local but persistent

If you tried multiple browsers, networks, and DNS settings and the issue still appears on one machine, your local environment may need deeper support.

Contact your registrar or host when the issue looks domain-related

If the domain fails everywhere, or the nameservers, DNS records, or domain status look wrong, escalate to the registrar or hosting provider.

Gather these details first

Before contacting support, note:

the exact domain
the browser and device
whether the issue appears on multiple networks
whether the domain was recently changed
any DNS settings you already updated

This makes support faster and reduces back-and-forth.

DNS_PROBE_FINISHED_ NXDOMAIN FAQs

Not always. It means the domain is not resolving correctly, which can happen even if the server itself is still running.

Yes. Some extensions can interfere with browsing, DNS lookups, or proxy behavior and trigger connection errors.

Yes. Changing from Wi-Fi to mobile data, or trying a different network, can help confirm whether the issue is tied to your local connection or DNS provider.

It depends on where the problem is. Contact your registrar for domain, nameserver, or renewal issues, and contact your hosting provider if the domain points correctly but the site still does not load.

Fixing DNS_PROBE_FINISHED_ NXDOMAIN

DNS_PROBE_FINISHED_NXDOMAIN usually means the browser cannot resolve the domain, whether because of a local DNS issue, a browser or network setting, or a domain configuration problem.

A good first step is to figure out whether the problem is local or domain-wide by testing the site on another browser, device, or network. That one check narrows the problem fast and tells you which fixes to try next.
