How do I resolve the ACM certificate "validation time out" error?

1 minute read

I requested an AWS Certificate Manager (ACM) certificate for my domain, but the request failed with a "validation time out" error.


If ACM certificate requests aren't validated within 72 hours from the time of the request, then the requests fail with the "validation time out error". To resolve this error, first delete the failed ACM certificate. Then, request a new ACM certificate.

To troubleshoot ACM certificate validation issues, see Troubleshoot DNS validation problems and Troubleshoot email validation problems.

Why is the CNAME record not resolving for my ACM issued certificate and the DNS validation status is still pending validation?

Why didn't I receive the validation email to issue or renew ACM certificates?
