Errors such as this will cause downtime and revenue loss, so you must fix them as soon as possible, and this guide will help you do that.

What is Error 1001: DNS resolution error?

  • This error appears when a web request is sent to Cloudflare for a non-existing domain or if the DNS provider is unavailable.
  • An external domain that is not on Cloudflare but has a CNAME record to an active Cloudflare domain can cause this issue.
  • If the target of the DNS CNAME record can’t be resolved, you’ll encounter this error message.
  • The Always Online feature is enabled for the Custom Hostname domain and that can lead to issues.
