CNAME entry not working on NameCheap using Amazon Certificate Manager

I am trying to set up a few SSL certificates in Amazon Certificate Manager, but I am trouble getting them verified after adding the CNAME in Namecheap.

Here is an example of the CNAME verification entries at Amazon Certificate Manager

Here is an example of another domains CNAME entry at Namecheap

If I put the entire value of the Name entry into Host at Namecheap, the verification fails. I also get an error on some long domains I have, as the Name entry exceeds 60 characters.

Can anyone assist with the correct parts needed to verify via DNS using Namecheap?

What is certificate Cname?

The Common Name (AKA CN) represents the server name protected by the SSL certificate. The certificate is valid only if the request hostname matches the certificate common name. Most web browsers display a warning message when connecting to an address that does not match the common name in the certificate.

How long does it take to validate ACM certificates?

After you write the DNS record or have ACM write the record for you, it typically takes DNS 30 minutes to propagate the record, and it might take several hours for Amazon to validate it and issue the certificate. During this time, ACM shows the Validation status as Pending validation.

How do I validate ACM certificates?

To set up DNS validation in the console Open the ACM console at https://console.aws.amazon.com/acm/ . In the list of certificates, choose the Certificate ID of a certificate with status Pending validation that you want to configure. This opens a details page for the certificate.

In the CNAME record enter - _cff0cda88701846cbe7a34cd737378e2 as the host field and - _490287b8f448e2cca3862ebb4a51591.acm-validations.aws in the value field.

Once done wait for at least 1 hour for the changes to reflect.
