there are currently two cert files which are used for i-mscp:
- one for services (ftp, postfix, dovecot)
- and one for the i-mscp admin control panel via nginx
Both certificates are located at "/etc/imscp/". The one from the services is named "imscp_services.pem" and the one for the admin control panel always has the name of the admin panel address (e.g. admin.domain.tld.pem).
In my eyes it would be easier (e.g. for the letsencrypt plugin) to use a static name for the i-mscp nginx cert too.
