Why did my ACM certificate request fail?
I requested a certificate through AWS Certificate Manager (ACM), but the request failed.
Resolution
Available contacts
If you use email validation to request a certificate provided by ACM, then make sure that your domain is configured to receive emails. Your domain's name server must have a mail exchanger (MX) record so that ACM's email servers know where to send the domain validation email to. ACM sends the validation email messages to the following five common administrative addresses:
- admin@
- administrator@
- hostmaster@
- webmaster@
- postmaster@
ACM adds each administrative address before the requested domain name. For more information, see Troubleshoot email validation problems
Additional verification required
If you receive the "Additional Verification Required" error message, then use the AWS Support Center to contact AWS Support. If you don't have a support plan, then post a new thread in the ACM discussion forum.
For more information, see Error message: Additional Verification Required.
Public domains that aren't valid
When the requested certificate includes a public domain that isn't valid, the certificate request fails and you receive the following error: "One or more domain names is not a valid public domain"
To resolve this error, request a new certificate. Make sure that the top-level domains of all domains specified in this new certificate's domain scope are valid.
For more information, see Error Message: Invalid Public Domain
Amazon-owned domains
If the requested certificate includes an Amazon-owned domain, such as domains that end in amazonaws.com, then the certificate request will fail with the following error: "Additional verification required to request certificates for one or more domain names in this request."
To resolve this error, request a new certificate with a domain name that isn't owned by Amazon.
For more information, see Error message: Additional Verification Required.
