I am trying to point a (sub)domain name purchased external to AWS to an application hosted in AWS via CloudFront with a ELB in front of it. The external domain has SSL and the AWS CloudFront-hosted application has a separate certificate installed already. Basically, I'm looking to white label the external subdomain and I'm curious how to go about making the external subdomain certificate work with the CloudFront application. Ultimately, I want the certificates to show as valid in a browser.
Currently, the domain name has a CNAME to another domain where the website is hosted. The domain name is showing the certificate from domain name the CNAME is pointed at presently in a browser. As a result, I'm seeing the following in Chrome for example:
Certificate - missing
This site is missing a valid, trusted certificate
(net::ERR_CERT_COMMON_NAME_INVALID).
I believe I need to use an alternative CNAME in CloudFront paired with a SAN on the certificate, but I am unsure how to do this at the moment.
