My VirtualHost redirects for an HTTPS site are broken - apache

Question

Apache/2.2.15, CentOS Linux.
I have a site where I want the whole site to be SSL-encrypted all the time. Normally, I don't use mod_rewrite to do my www/non-www redirects; I just use VirtualHosts and the Redirect directive.
Trying to do this with my HTTPS site, however, is returning a generic SSL connection error in all browsers. Here's my vhost file (domain names and IP addresses changed):
NameVirtualHost 192.168.0.256:80
NameVirtualHost 192.168.0.256:443
<VirtualHost 192.168.0.256:80>
ServerName www.example.com
ServerAlias example.com
Redirect / https://www.example.com/
</VirtualHost>
# ############################
# This block breaks everything

<VirtualHost 192.168.0.256:443>

Redirect / https://www.example.com/
</VirtualHost>
<VirtualHost 192.168.0.256:443>

ServerName www.example.com:443

</Files>
</VirtualHost>
The block marked "This block breaks everything" appears to be the culprit. When that VirtualHost block is commented out, the site loads as expected and everything's fine. But I really want/need to redirect non-www to www, and when that block is enabled, I get this on every attempt to load the site:
Error logs don't seem to show anything useful. Can anyone tell from this what exactly is going wrong?

Answer 1

Port 443 always needs a certificate attached to it. Even if its just a simple redirect. Connect -> SSL -> Data transfer.
