How to configure SSL for billmanager?

Question

ISPmanager

Articles even do not help me, they only mislead me. I bought Comodo PositiveSSL and tried to set it up for subdomains manually ( https://my.site.ru/billing,https://cp.site.ru/ispmgr ) according to the instructions, but it doesn't work.
I found a video, but there the setting goes through the ispmanager web interface, set it up for site.ru. Everything is working. For billmanager
and ispmanager, this setting does not work because port 443 is used, and panels are available at 1500

Answer 1

If the control panel (it doesn't matter BILLmanager or ISPmanager) works through the built-in ihttpd web server, then here is the documentation for setting it up - ru.5.ispdoc.com/index.php/%D0%9D%D0%B0%D1%81%D1 %82...
That is, you use the certkey and cert directives.
If the panel works through nginx, then install the certificate in nginx itself. ssl_certificate_key and ssl_certificate directives
