I am looking for clarification/guidance on the following.
www.example.com installed on CMS powered by Cloudflare CDN.
I want to secure subdomains used for other applications hosted on separate servers (non Cloudflare):
The CMS powered by Cloudflare has an SSL certificate issued for
www.example.com, and tells me that existing certificates cannot be repurposed for their system and their certificate cannot cover content not hosted by them.
My understanding is unless this certificate is not installed on the main domain (
www.example.com) we cannot apply on other sub-domains. Is that correct?
In other words, is it possible to have the CMS-provided certificate under
www.example.com on their server and use a wildcard certificate to secure all other subdomains on separate servers at the same time?
