Server Name Indication (SNI)
 

Server Name Indication (SNI) works with ISPmanager very well except that ISPmanager does not create the necessary NameVirtualHost directives for the port 443. Could you please check whether it's possible to create them (like the ones for port 443) automatically?

Are you have enabled SSL checkbox for user and www domain?

Yes, sure. Otherwise I should not be allowed to setup SSL for the domain ;-)
The <VirtualHost 192.168.0.1:80> container is also created but ISPmanager simply does not created a "NameVirtualHost 192.168.0.1:443" directive for SSL sites. This is of course not necessary if you do not configure multiple SSL sites per IP, but if you host several sites on the same IP address using SNI a NameVirtualHost statement (like the one which is created for port 80) is required.

btw version: ISPmanager-Pro 4.3.57.9
