Will AutoSSL cover service subdomains of an alias domain?

Question

Will AutoSSL cover service subdomains of alias domains?

Answer

AutoSSL will not cover the service subdomains of an alias domain. The service subdomains are not added to the Apache VirtualHost Configurations for domains added to cPanel as an alias. This is to reduce the number of domains required for a single SSL certificate. If you would like AutoSSL to cover an alias domain's service subdomains, you will need to remove the domain as an alias and add it as an addon domain.
