How to Fix DNS_PROBE_FINISHED_NXDOMAIN Error on Chrome

You’re typing a web address, hit enter, and instead of a page loading you see a wall of text starting with “DNS_PROBE_FINISHED_NXDOMAIN” — a sinking feeling familiar to millions of Chrome users — but it’s almost always fixable without calling a technician. You’ll learn what the error actually means and walk through a clear set of steps to get back online, from a simple cache flush to more advanced solutions.

Error name: DNS_PROBE_FINISHED_NXDOMAIN ·
Meaning: DNS probe completed, domain does not exist ·
Common causes: Incorrect DNS settings, corrupted cache, server issues ·
Affected browsers: Chrome, Edge, Chromium-based ·
First step: Restart browser and computer

The table below provides a quick reference to the error’s key attributes.

What Does DNS_PROBE_FINISHED_NXDOMAIN Mean?

Definition of NXDOMAIN

NXDOMAIN stands for “non-existent domain.” When Chrome’s DNS probe runs, it asks a DNS server to translate a domain name into an IP address. The server responds that the domain doesn’t exist — hence the error. According to IONOS Digitalguide (web hosting and domain guide), this indicates the DNS server could not find any matching IP for the domain.

Common causes of the error

• Misconfigured DNS settings on your device or router
• Corrupted DNS cache stored locally or in Chrome
• The website’s server is down or the domain has expired
• Browser extensions interfere with DNS resolution
• Antivirus or firewall software blocks DNS queries

The implication: many causes lie on your side of the connection, which means you have the power to fix them.

The implication: Chrome’s separate DNS cache makes it more prone to this error.

How Do I Fix DNS_PROBE_FINISHED_NXDOMAIN?

1. Flush DNS cache
2. Change DNS servers
3. Reset Chrome settings
4. Check host file

Flush DNS cache

The DNS cache stores past lookups so your computer doesn’t ask the server every time. But stale or corrupt entries trigger the NXDOMAIN error. Flushing wipes the slate clean.

• Windows: Open Command Prompt as administrator and run ipconfig /flushdns. According to Easy Tech Steps YouTube tutorial, this clears the system cache in seconds.
• macOS: Open Terminal and run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. Hostinger Academy (web hosting education) confirms this works for macOS Ventura and later.
• Chrome’s own cache: Type chrome://net-internals/#dns in the address bar and click “Clear host cache.” Plesk Blog (web platform provider) notes Chrome’s separate DNS cache often requires this manual step.

Change DNS servers

Your ISP’s DNS servers might be slow or unreliable. Switching to a public DNS provider often resolves the error permanently. Five providers, one pattern: all are free, public alternatives with better uptime than most ISP resolvers.

To change DNS on Windows: Go to Network Settings > Change adapter options > right-click your connection > Properties > Internet Protocol Version 4 (TCP/IPv4) > Use the following DNS server addresses. Enter 8.8.8.8 and 8.8.4.4.

On macOS: System Preferences > Network > Advanced > DNS > click + and add 1.1.1.1 and 1.0.0.1. Hostinger Academy demonstrates the process.

Reset Chrome settings

Chrome flags and experimental features can interfere with DNS handling. Type chrome://flags in the address bar and click “Reset all” to restore defaults. If the error persists, reset Chrome to factory settings via Settings > Advanced > Reset and clean up > Restore settings to their original defaults. Plesk Blog recommends this as a mid-level fix.

Check host file

The hosts file maps domain names to IP addresses before DNS lookup occurs. A bad entry here can force the NXDOMAIN result. IONOS Digitalguide warns that malware or previous tests may leave incorrect entries.

• Windows location: C:\Windows\System32\drivers\etc\hosts. Open in Notepad as administrator, look for lines mapping the domain you’re trying to reach, and delete them.
• macOS location: /etc/hosts. Edit with sudo nano /etc/hosts in Terminal and remove suspicious entries.

The catch: a single stray hosts entry can override every other DNS fix you try, so always inspect this file before moving to advanced solutions.

How Do I Fix DNS Errors on Chrome?

Enable secure DNS

Secure DNS (DNS-over-HTTPS) encrypts your DNS queries, preventing ISPs from intercepting or tampering with them. In Chrome, go to Settings > Privacy and security > Security > Use secure DNS. Choose a custom provider like Cloudflare (1.1.1.1) or Google (8.8.8.8). According to a Google Chrome Help Forum thread, users report success after enabling this feature.

Clear browser cache and cookies

Corrupted cached data can trigger DNS errors. Clear it via chrome://settings/clearBrowserData, select “Cached images and files,” and click “Clear data.” Include “Cookies and other site data” if you’re willing to re-login to websites.

Disable problematic extensions

Some Chrome extensions, especially VPN, ad-blockers, and proxy tools, alter how DNS requests are handled. Disable all extensions temporarily: go to chrome://extensions and toggle them off. If the error disappears, re-enable one at a time to find the culprit.

What this means: Chrome’s extension ecosystem is powerful but each add-on adds a potential friction point with DNS resolution. Treat extensions as the first suspect if you’ve already flushed caches.

How Do I Reset My DNS on Chrome?

Flush DNS cache on Windows/Mac

On Windows, run Command Prompt as administrator and type:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset

Easy Tech Steps confirms this full sequence resets the entire network stack. On macOS, use sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder followed by a restart.

Renew IP address

Releasing and renewing your IP address forces your router to assign a new lease, which can clear out old DNS configuration. On Windows, after the flush commands above, ipconfig /renew completes the cycle. On macOS, go to System Preferences > Network > Advanced > TCP/IP > Renew DHCP Lease.

Why this matters: a stale IP lease sometimes carries DNS settings that point to a defunct server, so renewing it closes the loop on DNS corruption.

What Is a DNS Error and How to Fix It?

Definition of DNS error

DNS — Domain Name System — is the internet’s phonebook. It translates human-readable domain names (like google.com) into machine-readable IP addresses. When DNS fails, your browser can’t connect to the server even if the website is perfectly healthy. The DNS_PROBE_FINISHED_NXDOMAIN error is one specific flavor of this failure.

General troubleshooting steps

When any DNS error appears, start with the broadest fixes before drilling down:

• Restart your router and computer — this clears temporary glitches.
• Test on another device to see if the problem is network-wide.
• Temporarily disable antivirus or firewall — some security suites overzealously block DNS queries. IONOS Digitalguide lists this as a key diagnostic step.
• Check your ISP’s status page for outages in your area.
• If nothing works, consider using a free VPN to bypass your ISP’s DNS entirely — though IONOS notes this is a temporary workaround, not a fix.

The pattern: the further you move from a simple cache flush to deeper network changes, the more likely the root cause is something other than a corrupt cache. If none of these steps work, you may be facing ISP-level DNS blocking or malware interference.

Other fixes for specific platforms

Android

On Android, go to Settings > Wi-Fi > tap your connected network > Modify network > Advanced options > IP settings > Static. Manually set DNS 1 to 8.8.8.8 and DNS 2 to 8.8.4.4. Alternatively, in Chrome for Android, type chrome://net-internals/#dns and clear the host cache.

macOS

Beyond the terminal flush commands, macOS users can edit the hosts file via sudo nano /etc/hosts in Terminal. If you find entries redirecting domains to 127.0.0.1 or other local IPs, remove them. Hostinger Academy walks through this step.

Edge (Chromium)

Since Edge is also Chromium-based, the same fixes apply. Clear the browser’s DNS cache via edge://net-internals/#dns, flush the system cache, and change DNS settings using the same methods as Chrome.

The catch: platform-specific instructions are easy to follow and often resolve the error.

The implication: while most fixes are well-documented, the underlying cause remains elusive in some cases.

What users say about fixing this error

“I was getting this error every day. Enabling secure DNS in Chrome settings fixed it immediately — haven’t seen it since.”

— User in Google Chrome Help Forum (community support thread)

“After flushing DNS from the command line and switching to 8.8.8.8, the error stopped completely. I should have done this months ago.”

— Comment in Easy Tech Steps YouTube tutorial

The evidence from real users underscores the effectiveness of basic DNS troubleshooting.

Summary

The DNS_PROBE_FINISHED_NXDOMAIN error is almost never a hardware failure — it’s a handshake problem between your computer, your browser, and the global DNS system. Most users resolve it in under five minutes with a cache flush and a DNS provider switch. For Chrome users on Windows or Mac, the combination of system-level flush, Chrome’s internal cache clear, and a switch to Cloudflare or Google DNS covers virtually all standard cases. If the error returns frequently, the root cause may be faulty router firmware or ISP-level DNS filtering, both of which require deeper network intervention. For the average user who just wants to get back to browsing, the steps in this guide — in order — will have you online faster than a support call ever could.
