I am experiencing an issue with the free TLS certificate signed by Cloudflare and installed on my origin server. (which is a load balancer) This cert is setup as a wildcard. (*.xxx.com)
When I navigate to sites that are 1 subdomain level everything works fine. (xxx.xxx.com)
However when I go to a site that is 2 or more subdomain levels (xxx.xxx.xxx.com) I get a cert error saying my connection is not secure and references the Origin Cert.
I believe this is an issue because I am using the free tier and I wanted to confirm if this is correct? and if so what is the best way to resolve this? is it to change my subscription to Pro or might there be other options?
