I have one AWS ec2 server. 2 Route53 domain names. One domain name has successfully installed a Let’s Encrypt certificate. The other domain connects using http by way of a CNAME record to the original domain name. But id I try to access https:// I get an error. I would like the 2nd domain name to share that same certificate if possible. Do Subject Alternative Name (SAN) mechanisms work in this scenario? If so how do I configure it to work?
Thank you for any assistance you can provide.
