Hi, after a lot of rumble I finally managed to use Let's Encrypt SSL for ISPConfig control panel on my Ubuntu 12.04.5 LTS. It does NOT work in the means like enabling Letsencrypt via ISPConfig, but ok, I just wanted it to run on main domain. Ok, now ISPConfig works via https://cp.mydomain.com:8081 Now, how can I use the same cert for PHPMyAdmin? It is on same FQDN, but on regular 443 port: https://cp.mydomain.com/phpmyadmin BTW... as /phpmyadmin is an Alias for ANY domain, the above link works just perfect on HTTPS if domain has existing SSL certificate installed. I just want to do the same for my MAIN domain. I guess I just need to create some Symlinks to existing SSL keys, and modify config, but do not know which links in which directory and which config file to edit. Help appreciated.
