I have a webmin with hostname virtualmin.xxx.com
Then I have 2 virtual servers: one called virtualmin and the other xxx.domain.com
xxx.domain.com is set to Default Website for IP address.
I would like to change xxx.domain.com
to https://xxx.domain.com
but when I go to Server Configuration - SSL Certificate - Let’s Encrypt and enter my domain I get the following error:
