My domain is pending validation in AWS Certificate Manager

Configured *.mydomain.com using AWS Certificate Manager and is shown in Pending Validation for more than a day, even though CNAME records was published to AWS Route53 under the domain name. Everything seems appropriate but its not clear, why the domain is not getting validated

Note: Domain was created using AWS Route53 as well

When you register the new domain, Route 53 will automatically create a hosted zone with the correct NS records. You should be able to open the hosted zone in the console and see 4 NS records that point to AWS DNS servers. For example,

ns-1502.awsdns-59.org.
ns-1757.awsdns-27.co.uk.
ns-319.awsdns-39.com.
ns-621.awsdns-13.net.

You can try looking your newly registered domain against the name servers using the dig command. For example:

$ dig @ns-1502.awsdns-59.org mydomain.com
...
;; ANSWER SECTION:
mydomain.com.       21599   IN  NS  ns-1502.awsdns-59.org.
mydomain.com.       21599   IN  NS  ns-1757.awsdns-27.co.uk.
mydomain.com.       21599   IN  NS  ns-319.awsdns-39.com.
mydomain.com.       21599   IN  NS  ns-621.awsdns-13.net.

This will confirm that AWS DNS is resolving your domain correctly. You can also check another non-AWS DNS server. For example, you can check against any public DNS server, such as Google's public DNS server at 8.8.8.8:

$ dig @8.8.8.8 mydomain.com ns
...
;; ANSWER SECTION:
mydomain.com.       21599   IN  NS  ns-1502.awsdns-59.org.
mydomain.com.       21599   IN  NS  ns-1757.awsdns-27.co.uk.
mydomain.com.       21599   IN  NS  ns-319.awsdns-39.com.
mydomain.com.       21599   IN  NS  ns-621.awsdns-13.net.
...

You should also see status: NOERROR in the output. If you instead see status: NXDOMAIN, it means that the domain really does not exist. In that case, you should review the AWS documentation on registering domain names, and in particular the troubleshooting docs. Make sure that you have clicked the confirmation link that was sent to your email when you registered the domain.

If your domain is registered correctly, you should be able to use DNS validation. Once you've requested the certificate with DNS validation and added the CNAME to the domain, you can check that it exists:

$ dig <your validation record>.mydomain.com
;; ANSWER SECTION:
<your validation record>.mydomain.com. 299 IN CNAME <some random value>.<some random value>.acm-validations.aws.

If you can resolve this using any public name server, then the validation record is set up correctly and you'll just have to wait. When it works, it's usually quite fast, but it can take up to 30 minutes.

With that said, I have occasionally seen the validation never complete, and the ACM certificate would remain in the pending state indefinitely. In that case, the only way to resolve it is to delete the certificate, request a new one, and try again. Note that if you do try again, the Route 53 validation CNAME record that they will ask you to create will always be the same.
