I've read a lot of threads o nthis forum, but non of them have a clear answer for my issue... So I have a SSL certificate, installed it for one of my websites in the ISPConfig 3 contorlpanel... I also enabled SSL on the main config screen of the website... But whenever I go to https://domain.nl(:443) IE gives me the error: Internet Explorer cannot display the webpage. /etc/apache2/apache2.conf is listening to port 443... but why is it still not working?
