It seems that the Satellite 6.2 Beta install process installs the mod_ssl package but deletes /etc/httpd/conf.d/ssl.conf.  Everything works fine until mod_ssl is updated via a yum update. Because ssl.conf is missing, mod_ssl re-creates the default file, resulting in a conflict within httpd as the Listener for port 443 is now defined twice, end result is httpd fails to start and Satellite WebUI is not available.

I have two 6.2 Beta instances:

Satellite 1 (not updated):
root@sat62-1[/etc/httpd] # rpm -q mod_ssl
mod_ssl-2.4.6-40.el7.x86_64
root@sat62-1[/etc/httpd] # grep -R 443 conf*
conf/ports.conf:Listen 443
conf.d/05-foreman-ssl.conf:<VirtualHost *:443>

This satellite has a pending update:
root@sat62-1[/etc/httpd] # yum check-update | grep ssl
mod_ssl.x86_64                   1:2.4.6-40.el7_2.1    rhel-7-server-rpms


My second 6.2 Beta satellite HAS had the yum update applied:
root@sat62-2[/etc/httpd] # rpm -q mod_ssl
mod_ssl-2.4.6-40.el7_2.1.x86_64
root@21t62-2[/etc/httpd] # grep -R 443 conf*
conf/ports.conf:Listen 443
conf.d/05-foreman-ssl.conf:<VirtualHost *:443>
conf.d/ssl.conf:Listen 443 https
conf.d/ssl.conf:<VirtualHost _default_:443>
conf.d/ssl.conf:#ServerName www.example.com:443

The /etc/conf.d/ssl.conf file should NOT be removed by the Satellite installer, but possibly modified to remove the Listen 443 directive... Alternatively the definition should be left in ssl.conf and removed from ports.conf
