Sorry if I couldn’t find my answer in the forum. We are providing a web hosting like service. Our customers may have the service on their own sub-domain by creating a CNAME record over their main domain pointing to our domain. Is there a way to DNS proxy our domain along with other sub-domains without need to move all those customer’s domains to cloudflare (which is impossible)? The problem is that our service is served only over HTTPS and all those sub-domains need to have HTTPS enabled.
For example assume our domain is
service-provider.com and there are lots of
sub.customer-y.com and etc pointing to
service-provider.com using CNAME record but they are not using cloudflare as DNS service. When enable the proxy for our domain, the HTTPS connection breaks for other sub-domains.
