DNS_PROBE_FINISHED_NXDOMAIN

If you or your visitors experience DNS_PROBE_FINISHED_NXDOMAIN errors after you activate your domain on Cloudflare, review your DNS records in Cloudflare.

​​ Background

DNS_PROBE_FINISHED means that the DNS request for a resource timed out and NXDOMAIN stands for non-existent domain. Together, these messages mean that the DNS query for a specific resource could not locate an associated domain.

Though visitors sometimes encounter this error — or similarly worded messages from Safari, Edge, or Firefox — because of network or local DNS issues, it might point to an issue with your DNS records in Cloudflare.

​​ Potential solutions

If you experience DNS_PROBE_FINISHED_NXDOMAIN errors with a newly activated domain, review your DNS settings in the Cloudflare dashboard.

Check your expected root domain (example.com) and any active subdomains (www.example.com or blog.example.com). If they do not resolve correctly, you may need to add a root domain record or a subdomain record in Cloudflare DNS.

If you have the correct records set up, make sure those records are also pointing to the correct origin IP address.

After making changes to your DNS records, you may need to wait a few minutes for those changes to take effect.
