I am running into issues, that a multi-level subdomain is not working with Cloudflare provided wildcard SSL, as the certificate itself only protects two levels of your domain, one is apex level, and another one is a subdomain of apex level.
The tree looks like this:
- example.org (Works!)
This is kinda frustrating when migrating large sites to Cloudflare, and is losing all the subdomains. My own SSO server stays at padlock.something.mydomain.com, and this is the case that Cloudflare Wildcard SSL is not working at all. Once I turn on the orange cloud for that DNS record, browsers immediately prompt SSL errors.
I am hoping there are people who can shed some lights on this, since it has been itchy long time ago.
