"make_sock: could not bind to address [::]:443" when restarting apache (installing trac and mod_wsgi)

I'm trying to install trac and mod_wsgi over SSL. I tried to manually install it, but that didn't work out so well so I started to follow this: trac-on-ubuntu

I skipped the svn part because I'd like to use git instead. After the first edit of httpd.conf:

WSGIScriptAlias /trac /var/trac/apache/trac.wsgi<Directory /var/trac/apache>    WSGIApplicationGroup %{GLOBAL}    Order deny,allow    Allow from all</Directory>

I restarted apache only to get this error:

* Restarting web server apache2                                                    (98)Address already in use: make_sock: could not bind to address [::]:443                                                                     [ OK ]

Doing these showed nothing.

 netstat -anp | grep 443  fuser 443/tcp

Doing this didn't yield anything except the grep command that I ran:

ps -aux | grep httpd

Why is it saying that something else is using the port when there's nothing showing up?

EDIT: You guys are going to laugh at this. I had an extra Listen 443 in ports.conf that shouldn't have been there. Removing that solved this.
