I am trying to get a certificate for a domain that do not have an A record (let it be mydomain.net) but it has a NS record to an IP resolvable domain (let it be example.com). Getting the certificate for example.com and using a service delegated on mydomain.net, I get an alert on my service clients that mydomain.net is not trusted. When I tried to get an certificate for mydomain.net, I got an error because it is not a resolvable domain. What I need to do?
My domain is:
I ran this command:
certbot certonly -d mydomain.net --standalone
It produced this output:
Detail: No valid IP address found for mydomain.net
My operating system is (include version):
I can login to a root shell on my machine (yes or no, or I don’t know): I have root access only on example.com
