    Hi guys!
    I just installed ISPConfig on a virtual server as per the Perfect Server Debian 12 + ISPConfig guide.
    Everything works perfect (webmail, https redirect, DNS is properly configured, server can be reached with FQDN), except the ISPConfig control panel.
    I permanently receive a warning message "Privacy Error: NET::ERR_CERT_COMMON_NAME_INVALID".
    Looking into the certificate details it looks OK to me.
    I tried (I believe) every suggestion related this matter, even reconfiguring and updating ISPConfig, but haven't succeeded.
    Any suggestion would be welcomed.

    Thanks.

    The ssl cert is issued for the systems hostname, you can see that hostname by running this command on the shell of your server:

    hostname -f

    and you must use this hostname to connect via your browser. Example:

    https://hostname:8080

    where hostname is the exact name the above command returned.
