Red Hat httpd ssl config

Okay, I have a site setup on port 443 in ssl.conf file.  The issue is, I cannot start the service httpd (apache2) I get the error:

no listening sockets available, shutting down



Then, when I run sudo netstat -anp | grep 443

tcp     0     0.0.0.0:443       0.0.0.0:*         LISTEN         3544/httpd

How can I find what is running on 443 so I can start my site?  I am not seeing any other website but may be missing something.
