Certificate Common Name (CN) and Hostname Match error

[psingh]

Hi
our letsencrypt is generating certs on our hostname instead of domain.

in another thread, a user has asked building vhosts, but we cannot find the option to build vhosts in our panel. there is an option to Rebuild Apache but no option as Apache settings in the latest version we are on. wiki is asking to search somewhere in apache settings, but option does not exist in our panel.

pls help to fix this

thanks
