"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](http://robertbasic.com/blog/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.
