Apache: Why can I access my site at example.com:443 and NOT at https://example.com?

I've created a self-signed SSL certificate via OpenSSL and have configured it for Apache.

For some reason, I can NOT access my site at:

https://alwaysbaked.net

I believe that I have Apache configured correctly because I can access the following:

http://alwaysbaked.net:443

Also, when I start Apache, I get the following message:

* Starting web server apache2 Apache/2.2.8 mod_ssl/2.2.8 (Pass Phrase Dialog)
Some of your private key files are encrypted for security reasons.
In order to read them you have to provide the pass phrases.
Server alwaysbaked.net:443 (RSA)
Enter pass phrase:
OK: Pass Phrase Dialog successful.

My CONF stub looks like this:

NameVirtualHost *:443
<VirtualHost *:443>
      DocumentRoot /var/www/alwaysbaked.net/
      ServerName alwaysbaked.net
      ServerAlias www.alwaysbaked.net
      SSLEngine On
      SSLCertificateFile /etc/ssl/certs/server.crt
      SSLCertificateKeyFile /etc/ssl/private/server.key
</VirtualHost>

I used this tutorial to create the certificate:

https://help.ubuntu.com/8.04/serverguide/C/certificates-and-security.html

I used this tutorial to configure the certificate for Apache:

https://help.ubuntu.com/8.04/serverguide/C/httpd.html#https-configuration

I don't think the problem is a firewall issue. HTTPS should be open to the outside world, because it's apparent that port 443 is open (I believe that HTTPS uses port 443 for incoming/outgoing communication). Also, my domain is registered at GoDaddy.com, so I'm not sure if they block HTTPS in some way.

Can someone take a look at this and point me in the right direction?

Thanks!
