Fix “DNS_PROBE_FINISHED_NXDOMAIN” error

Fix "DNS_PROBE_FINISHED_NXDOMAIN" error

What does this error mean?

The "DNS_PROBE_FINISHED_NXDOMAIN" error means the browser couldn't find the domain in DNS servers. This usually indicates that the domain doesn't exist, isn't configured correctly, or there's a problem with DNS configuration.

Common causes

• ❌ Domain is not configured in nameservers
• ❌ DNS records are not configured correctly
• ❌ Domain expired
• ❌ Nameservers are incorrect
• ❌ DNS propagation issues
• ❌ Corrupted local DNS cache

Solution 1: Verify domain exists

First, verify that the domain is active:

whois yourdomain.com

Verify:

• That the domain is not expired
• That the status is "active" or "ok"
• That nameservers are configured

Solution 2: Verify DNS records

Verify that DNS records are configured:

nslookup yourdomain.com
dig yourdomain.com

If there are no results, it means no A records are configured.

What to do:

• Log in to your domain's DNS panel
• Verify that an A record exists for the main domain (@)
• If it doesn't exist, add it with the correct server IP
• Save the changes

Solution 3: Verify nameservers

Verify that nameservers are correct:

whois yourdomain.com | grep "Name Server"
dig NS yourdomain.com

If nameservers are incorrect or not responding:

• Verify that they are configured correctly in your registrar
• Contact your hosting provider if you use their nameservers
• Verify that nameservers are active

Solution 4: Clear local DNS cache

Your computer's DNS cache may have outdated information:

Windows:

ipconfig /flushdns

macOS:

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder

Linux:

sudo systemd-resolve --flush-caches

After clearing the cache, try accessing the domain again.

Solution 5: Verify DNS propagation

If you just made DNS changes, they may not have propagated yet:

• Use tools like whatsmydns.net or dnschecker.org
• Verify from different locations
• Wait up to 48 hours for complete propagation

Solution 6: Verify from different DNS servers

Try querying the domain from different DNS servers:

nslookup yourdomain.com 8.8.8.8
nslookup yourdomain.com 1.1.1.1
nslookup yourdomain.com 208.67.222.222

If some servers respond and others don't, it's a propagation issue.

Solution 7: Verify configuration in panel

If you use cPanel or similar panel:

• Verify that the domain is added correctly
• Verify that DNS records are saved
• Check for syntax errors
• Verify that the server IP is correct

Solution 8: Change DNS temporarily

If the problem persists, try temporarily changing your computer's DNS:

Windows:

• Network settings → Change adapter options
• Properties of your connection → Internet Protocol Version 4
• Use the following DNS server addresses:
  • Preferred DNS: 8.8.8.8
  • Alternate DNS: 8.8.4.4

This will help determine if the problem is with your local DNS provider.

Step-by-step verification

1. Verify domain is active:

whois yourdomain.com

2. Verify DNS records:

dig yourdomain.com

3. Verify nameservers:

dig NS yourdomain.com

4. Verify from different DNS:

dig @8.8.8.8 yourdomain.com

5. Clear local cache:

ipconfig /flushdns  # Windows
sudo dscacheutil -flushcache  # macOS

Specific problems

Domain worked before but now it doesn't

• Verify if the domain expired
• Check if recent DNS changes were made
• Verify if you changed hosting or nameservers
• Contact support if the problem persists

Domain works in some places but not others

• It's a DNS propagation issue
• Wait for propagation to complete (up to 48 hours)
• Verify with DNS propagation tools

Domain works with IP but not with name

• It's definitely a DNS problem
• Verify that A records are configured
• Verify that nameservers are correct

Preventive tips

• ✅ Regularly verify that your domain is not about to expire
• ✅ Keep a copy of your DNS configuration
• ✅ Verify configuration after making changes
• ✅ Use automatic renewal if available
• ✅ Monitor your domain status regularly
