I activated SSL on my website this afternoon.
I state that we have a second level domain and a third level domain.
At registration, only the second level domain can be entered, but in the settings it says that both are covered.
Currently entering the second level site, I see that the certificate is read correctly.
If I enter the third-level site, it tells me that the connection is not secure and therefore does not detect it. It still takes time? 24 hours? or is the SSL certificate not managed on third level domains?
