I’d like to understand this a bit more… I tried myself to activate CloudFlare on a subdomain. A few hours ago I went to my control panel account, activated CF on a subdomain (
cftest.example.com) for the first time. I didn’t have a CF account, created everything new: there is no CF on my domain
example.com. After a few hours, I see that the DNS records for
cftest.example.com are showing
On CloudFlare side, I’m waiting for a SSL certificate to be issued (see image below). Is this SSL the one that you’re saying never arrived?
