DNS_PROBE_FINISHED_NXDOMAIN Meaning

DNS_PROBE_FINISHED_NXDOMAIN is a DNS-related error that appears when a browser cannot find any DNS record for the domain name being requested. In simple terms, the DNS system is saying that the domain does not exist or cannot be resolved to an IP address. This prevents the browser from connecting to the website.

This error can be caused by anything from a simple typo in the domain name to incorrect DNS records, nameserver misconfiguration, misuse of custom NS settings, or local network issues. While it often looks like a server-side problem, it can also occur entirely on the visitor’s device.

1. A typo in the URL
   
2. Using the wrong domain extension (for example, .com instead of .net)
   
3. Accessing a domain that has expired or was never registered
   

1. No A, AAAA, or CNAME record exists for the domain or subdomain
   
2. DNS records point to an incorrect or inactive IP address
   
3. DNS records were accidentally deleted or misconfigured
   
4. Improper DNS load balancing service configuration causing records to resolve inconsistentl3. Nameserver Misconfiguration

1. Domain nameservers are not set correctly at the registrar
   
2. Nameservers do not match the DNS provider in use
   
3. Recent nameserver changes have not fully propagated
   
4. Missing or incorrect subdomain NS delegation

1. DNS changes can take time to propagate globally
   
2. Some networks may still be using cached, outdated DNS data
   

1. ISP DNS servers are temporarily unavailable or outdated
   
2. Corrupted DNS cache on the device
   
3. VPN, firewall, or security software interfering with DNS resolution
   

1. The domain is in the middle of a transfer between providers
   
2. Hosting or CDN was changed, but DNS records were not updated accordingly
   

1. DNSSEC enabled without correct DS records at the registrar
   
2. Mismatched or expired DNSSEC keys causing validation failure, which may appear as NXDOMAIN
   

1. Double-check the domain spelling in the browser.
   
2. Confirm the domain is registered and not expired.
   
3. Use a DNS lookup or DNS checker tool to see if the domain resolves anywhere.
   

1. Ensure the domain has been successfully added to your Verge Cloud account.
   
2. If the domain was recently transferred, wait up to 24 hours for the transfer and DNS propagation to complete.
   
3. Use a DNS checker to confirm that Verge Cloud nameservers (NS records) are correctly set at your domain registrar.
   

1. Confirm that the nameservers set at your domain registrar match your DNS provider.
   
2. Avoid mixing nameservers from multiple providers.
   
3. Allow time for propagation after any changes.
   

1. Verify that your domain is using Verge Cloud’s assigned nameservers.
   
2. Ensure there are no extra or outdated nameservers still configured at the registrar.
   
3. After updating nameservers, allow sufficient time for global DNS propagation.
   

1. Ensure the domain has valid DNS records:
   

1. Log in to the Verge Cloud panel and open the DNS management section.
   
2. Confirm that the root domain (example.com) or subdomain (www.example.com) has an active DNS record.
   
3. Verify that A or CNAME records point to the correct source IP or hostname.
   
4. Ensure the Cloud Icon (CDN acceleration) is enabled if required for your setup.
   

1. Confirm that the specific subdomain you are trying to access actually exists in DNS.
   
2. Remember that subdomains require their own DNS records.
   
3. Do not assume www works automatically if it is not configured.
   

1. In the Verge Cloud panel, verify that a DNS record exists for each subdomain.
   
2. If missing, create the appropriate A or CNAME record.
   
3. Confirm the subdomain is properly linked to your application or origin server.
   

1. Clear the DNS cache on your device.
   
2. Restart your router or modem.
   
3. Switch to a public DNS resolver such as:
   

1. This step mainly applies to visitors, but Verge Cloud users can:
   

6. Check for Firewall, VPN, or Security Interference

General solution

1. Temporarily disable VPNs or security software and test again.
   
2. Ensure firewall rules are not blocking DNS queries.
   
3. Test the site on a different network (for example, mobile data).
   

Verge Cloud–specific steps

1. Confirm that Verge Cloud security or firewall settings are not blocking legitimate traffic.
   
2. Review any access rules or restrictions that may affect DNS resolution or origin connectivity.
   

1. Chrome and other browsers may show the same NXDOMAIN message as desktop.
   
2. Mobile network DNS issues or private DNS settings can trigger the error.
   

1. Safari typically shows “Cannot Open Page” or “Server Not Found.”
   
2. DNS issues may be caused by Wi-Fi settings, VPNs, or mobile carrier DNS.
   

1. Toggle airplane mode on and off.
   
2. Switch between Wi-Fi and mobile data.
   
3. Change DNS settings to a public DNS if supported.
   
4. Restart the device.
   

1. DNS propagation takes time: Changes may take minutes to several hours to be visible everywhere.
   
2. Nameservers must match your DNS provider: A mismatch is one of the most common causes of NXDOMAIN errors.
   
3. Every domain and subdomain needs a DNS record: Missing records will always result in resolution failures.
   
4. Test from multiple locations: This helps determine whether the issue is global or local.
