My custom domain name is not validating

If your domain is not validating, here are some common reasons.

The NAME requires a suffix

Some domain registrars require you to add the CNAME NAME with a suffix. If the NAME is abcdef , try adding it with your domain as the suffix (e.g. abcdef.mydomain.com).
Additionally, some domain registrars also require you to add a trailing . (dot) at the end.

Your CNAME updates haven't propagated yet

It can take some time for the CNAME records that you've applied to reflect across the internet.
You can use a tool like DNSChecker.org to check this.

Your domain provider requires you to add a CAA record

You may need to add an additional CAA record for successful validation:

Type: CAA
Name: @
Tag: issuewild
Flag: 0
CA Domain: amazon.com
