Hello, I have followed these pages: http://docs.ispconfig.org/creating-web-sites/subdomains/ http://docs.ispconfig.org/dns-basics/canonical-dns-records/ To create subdomain through Create Domain method. Name is like mantis.domain.mx But enabling SLL on that and using next page: https://www.howtoforge.com/community/threads/http-to-https-redirection.44209/ Modified Apache directives in order to force HTTPS on subdomain. Now the problem: Subdomain is now resolving to default "It works!" page using HTTPS, not ISPConfig 3 default page. Moreover, looking at apache vhost file there is no VirtualHost *:443 section. I think it is supposed that ISPConfig should modify vhost file, right? Or should I alter it manually? Besides, is the site SSL option supposed to set up that or am I missing something? Thanks in advance.
