I created a subdomain name which is from my hostdomain "sub.hostdomain" and each time i try to enable ssl for the hostdomain and sub.domain the Let's Encrypt validation status will indicate a 400 error whereas a different domain name that i added pointing to the same IP and NS as the hostdomain and sub.domain gets ssl assigned without error.

How can I resolve this issue? Please note that I have followed your steps to change the host domain to the domain name that got ssl enabled to see if that would resolve the issue but it got changed but the issue still persist.
