Got this message when I restarted the apache2 daemon after I added a new virtual host in/etc/apache2/sites-available/default-ssl on Ubuntu 10.04:

[warn] _default_ VirtualHost overlap on port 443, the first has precedence

I checked the other Apache config files and inside /etc/apache2/ports.conf there’s a comment on what to do:

Step 1. Add NameVirtualhost *:443 entry in ports.conf (inside <IfModule mod_ssl.c>)

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.
    NameVirtualHost *:443
    Listen 443
</IfModule>

Step 2. Change the VirtualHost statement in /etc/apache2/sites-available/default-ssl

Replace <VirtualHost __default__:443> with <VirtualHost *:443> (as mentioned in the comment inports.conf).

Step 3. Restart Apache and check if SSL is working fine for all of your virtual hosts
