Can't enable custom domain on Lightsail

Hi rdWebDev,

As you may already know, Lightsail distribution only accepts certificates that are created in the us-east-1 region.

InvalidInputException error usually indicates that the input data in your AttachCertificateToDistribution action does not conform to the validation rules for this action. When you create the A record for your domain use your root domain (e.g, domain.com) to point to your distribution and also create a CNAME record using your subdomain (e.g. blog.domain.com) to points to your distribution. For more information on how to enable custom domain in Lightsail refer to this documentation.

I hope this will help.

Hi rdWebDev,

The InvalidInputException you received indicates there may be a Cloudfront distribution that is already configured with one of the domain names associated with the certificate.

The resources linked above by @Cebi will also hopefully point you in the right direction.

Thanks for using Lightsail
