SSL install breaks apache service

[iraqiboy90]

The issue specifically happens when you install mod_ssl and then enable SSL in the sentora panel. What happens is that mod_ssl already created a file /etc/httpd/conf.d/ssl.conf with the "Listen 443 https" and then when you enable https from sentora panel, it also adds "Listen 443 https" to the httpd-vhosts.conf file. This is a conflict. There can't be two Listen lines of the same type across Apache config files.

You already fixed it somehow, but the easiest thing to do is uncomment the "Listen" line in the ssl.conf file and retry restarting apache
