Custom Domain fails to validate

Problem Statement

When trying to create a “custom domain” we selected the Auth0 managed certificates option and getting the error:

Error! Your verification record was not found. You might need to wait a few minutes before we can discover it.

Cause

Auth0-managed certificates do not support the use of a proxy.

Solution

When encountering the issue, review the following:

  1. It might take 48 hours or more for a custom domain to be validated.
  2. Use the ‘dig’ command line tool or MXToolbox to view the current state of the DNS setup and verify if the CNAME record is available.
  3. Go to Dig (DNS lookup) and input the custom domain. Verify that the CNAME record on the Auth0-managed certificate is the same as on the dashboard.
  4. Ensure that a proxy is not used in conjunction with the Auth0-managed certificates.
  5. If it has been more than 7 days after the Custom Domain was created in Auth0 and the validation is yet to be done (eg: due to delay in updating DNS), delete and re-create the Custom Domain. New values will be received for the DNS verification.

If the above items have been verified and the custom domain is still pending verification, wait four hours before reverifying the domain. Do not recreate the custom domain when reverifying to avoid interruptions to the service.

Since a proxy is not supported in conjunction with Auth0 managed certificates, consider the use of self-managed certificates .
