Introduction: Understanding the DNS_PROBE_FINISHED_NXDOMAIN Error

If you’ve ever tried to visit a website and instead saw this error:

DNS_PROBE_FINISHED_NXDOMAIN

…it means your browser was unable to find the domain you’re trying to reach. This is a common issue across browsers like Google Chrome, Edge, and even Firefox, especially on Windows 10/11 or macOS systems.

But what exactly does this cryptic message mean?

What Causes DNS_PROBE_FINISHED_NXDOMAIN?

This error occurs when the Domain Name System (DNS) lookup fails, specifically because the domain name doesn’t exist or cannot be resolved. Common causes include:

• Typo in the web address
• Outdated or misconfigured DNS settings
• Browser cache issues
• Faulty network connection
• Hosts file conflicts
• Router or ISP-related problems

In this comprehensive guide, we’ll explain what DNS_PROBE_FINISHED_NXDOMAIN really means and walk you through 9 expert-tested solutions, each with a real-world success rate, so you can fix it fast — no matter what device or OS you’re using.

Fix 1: Check and Correct the URL (Success Rate: ~95%)

Before diving into technical fixes, double-check that the URL you typed is correct.

Steps:

1. Look for typos like:

• googel.com instead of google.com
• facebok.com instead of facebook.com

1. Try pasting the link from a trusted source.
2. Use a search engine to navigate to the site instead.

Why It Works:

A large percentage of NXDOMAIN errors are due to simple typing mistakes.

---

Fix 2: Clear Browser Cache & Cookies (Success Rate: ~85%)

Your browser may be loading an outdated or corrupted version of the site’s DNS record.

Steps (Chrome Example):

1. Click the three dots > Settings.
2. Go to Privacy and Security > Clear Browsing Data.
3. Select:

• Time range: Last hour or All time
• Cookies and other site data
• Cached images and files

1. Click Clear data.

Repeat for other browsers if needed.

Why It Works:

Cached DNS entries may point to incorrect or outdated server locations.

Fix 3: Flush DNS Cache & Renew IP Address (Success Rate: ~90%)

Sometimes, your system holds onto incorrect DNS records.

Steps (Windows):

1. Open Command Prompt as Administrator.
2. Run these commands one by one:

   ipconfig /flushdns
   ipconfig /release
   ipconfig /renew
   netsh winsock reset
   netsh int ip reset

3. Restart your PC after running all commands.

For macOS:

sudo killall -HUP mDNSResponder
sudo dscacheutil -flushcache

Why It Works:

Resets local DNS cache and renews your IP configuration, forcing your system to fetch fresh DNS records.

Fix 4: Change Your DNS Server (Success Rate: ~80%)

Your current DNS server (often provided by your ISP) might be slow or unreliable.

Steps (Windows):

1. Press Win + R, type ncpa.cpl and press Enter.
2. Right-click your active connection > Properties.
3. Double-click Internet Protocol Version 4 (TCP/IPv4).
4. Select:

• Use the following DNS server addresses:
  • Preferred DNS server: 8.8.8.8
  • Alternate DNS server: 8.8.4.4

1. Click OK and restart your browser.

Use Google Public DNS, Cloudflare DNS (1.1.1.1), or OpenDNS for better reliability.

Why It Works:

Switching to a faster, more reliable public DNS improves resolution accuracy and speed.

---

Fix 5: Reset Network Settings (Success Rate: ~75%)

Corrupted network configurations can cause persistent DNS issues.

Steps (Windows):

1. Go to Settings > Network & Internet > Status.
2. Scroll down and click Network reset > Network reset now.
3. Choose “Reset this device” and confirm.

⚠️ Warning: This will remove saved Wi-Fi networks and Bluetooth devices.

Why It Works:

Resets all network adapters, drivers, and settings to default, eliminating deep-rooted issues.

---

Fix 6: Disable IPv6 (Success Rate: ~70%)

Some routers and ISPs don’t fully support IPv6, which can lead to DNS failures.

Steps (Windows):

1. Press Win + R, type ncpa.cpl and press Enter.
2. Right-click your active connection > Properties.
3. Uncheck Internet Protocol Version 6 (TCP/IPv6).
4. Click OK and restart your browser.

Why It Works:

Disabling IPv6 forces your system to use IPv4, which is more widely supported and stable.

---

Fix 7: Edit the Hosts File (Success Rate: ~65%)

The hosts file maps domain names to IP addresses manually. If it contains incorrect entries, it can block access to websites.

Steps:

1. Navigate to:

   C:\Windows\System32\drivers\etc\hosts

2. Open the file with Notepad (as Administrator).
3. Look for any lines containing the problematic domain.
4. Delete or comment them out by adding # at the beginning.
5. Save and restart your browser.

Why It Works:

Removes incorrect or malicious mappings that override DNS lookups.

---

Fix 8: Restart Your Router & Modem (Success Rate: ~80%)

Sometimes, the problem lies not with your computer but with your router or modem.

Steps:

1. Turn off your router/modem.
2. Wait 30 seconds.
3. Power them back on and wait for all lights to stabilize.
4. Reconnect your device and test the site again.

Why It Works:

Resets the network hardware and clears temporary glitches in DNS routing.

---

Fix 9: Contact Your ISP or Website Admin (Success Rate: ~100%)

If none of the above work, the issue could be with your Internet Service Provider (ISP) or the website itself.

Steps:

1. Try accessing the site from another network (e.g., mobile hotspot).
2. If it still doesn’t work, check tools like:

• DownDetector
• IsItDownRightNow

1. If the site is online, contact your ISP to report DNS issues.
2. If you own the site, contact your hosting provider or admin.

Why It Works:

Eliminates user-side issues and confirms whether the problem is external.
