Cname entry for podcast.mydomain.com is resolving to the desired location cloud.podbean.com but ssl isn't working

I have a domain: mydomain.com. It is hosted in Cpanel/WHM and I installed a regular SSL certificate on the server (comodo SSL). I added a cname entry to point "podcast" to https://cloud.podbean.com.

Visiting https://example.com works, but when I try to access the https://podcast.example.com

What am I doing wrong? Is this not possible to get it to work? Someone suggested I use a load balancer but, to be honest, I'm not very knowledgeable about managing the server. I use a VPS with root access and have to hack my way through stuff. Any help on clarifying this issue is truly appreciated!

Your explanation is not really clear enough to answer, but I'll just mention that a certificate is only valid when the site name matches exactly, and subdomains are not an exact match (unless you use a wildcard certificate).

A certificate for example.com is not valid for podcast.example.com.
