In my ISP Config I use RSPAND. I made a website in ISPconfig for it. But it is unsecure. So I created certificate and signed it with my selfsigned CA as I do for my other internal websites. The certificates .key and .crt are created but RSPAMD d site still unsecure. The rspmd.....host file has the correct path to the certificates. Why, shouldn't i work as at a normal site
It will work exactly as any other regular site if you use a website as reverse proxy for another service. There is no difference. Most likely the site can not be written due to custom config in Apache directives field or something similar. Check if the site has a .err file in the /etc/apache2/sites-available/ folder.
no err file, the .hosts file haas been modified by ISPconfig,the time stamp has the time I put the key etc in ISPconfig.
Ok, have you checked that the ssl key and certificate file of the website contain the same certificate you entered in ISPConfig? if not, you might have missed selecting "save certificate" in action field when saving the data on SSL tab.
