look for ssl.conf, mine is in the the same location as httpd.conf
this is the relevant part of the file
# When we also provide SSL we have to listen to the
# standard HTTP port (see above) and to the HTTPS port
# Note: Configurations that use IPv6 but not IPv4-mapped addresses need two
# Listen directives: "Listen [::]:443" and "Listen 0.0.0.0:443"
