Hello, I've installed ispconfig 3..0.5.4p5 on ubuntu server 14.04 LTS and NGINX. It's working perfectly. My server as its own domain name, let's say ita01.mydomainname.com and NO ssl certificate at the moment; I'll buy one soon. Then, I have one of my clients who has the mail.clientdomainname.com subdomain hosted on my server and they use it to access the webmail. The mail.clientdomainname.com has its own SSL certificate and the client can access https://mail.clientdomainname.com/webmail without problems. Now I'd like to allow the client to access the control panel via https://mail.clientdomainname.com:8080 When I type https://mail.clientdomainname.com:8080 , firefox throws a security exception saying the certificate is not valid. It's clear that it's using the self-signed certificate that has been created during ispconfig setup. How can I tell ispconfig to use the right certificate based on the domain used to access the control panel? Thank you. Kind Regards.
