Greetings! Well... Domain.com is ok in http! In https://domain.com, an error message shows up (see photo). Completely nothing is sent from the server, I think there is no connection at all (I use a firefox extension to look at the headers , there is nothing at all). Strangely, https://domain.com:12435 (port where ISPconfig is running) IS working! I have setup a SSL certificate for domain.com, with the Authority certificate, etc. Port 443 seems to be opened normally... Any suggestion?
