virtualhost - Apache cannot find virtual host if domain is the same as server FQDN

Within Apache I had a vhost set up with ServerName host1.example.com

Within /etc/hosts there is an entry for host1

127.0.1.1 host1.example.com host1

And in /etc/hostname

host1

This is the Debian/Ubuntu way of creating an FQDN.

Apache seems to have a problem when serving content for a virtual host that has the same FQDN as the server itself.

When running nginx with a vhost for host1.example.com it has no problem picking up the Host header and using the correct vhost.

But when using Apache it has problems, it always uses 000-default. Deleting 000-default makes it switch to the next vhost and deleting all but the vhost file for the domain that I want to work finally makes it work.

NameVirtualHost is set to *

There are no error messages in the logs, no overlapping virtualhosts and the vhost config is perfectly fine.

        ServerAdmin webmaster@localhost
        ServerName host1.example.com

        DirectoryIndex index.php index.htm index.html
        DocumentRoot /var/www/host1.example.com


        
            Options FollowSymLinks Includes -Indexes
            AllowOverride All
            Order allow,deny
            Allow from all
        

Anyone have any ideas?

Edit:

apache -t -D DUMP_VHOSTS output:

VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:*                    is a NameVirtualHost
         default server the.server.fqdn (/etc/apache2/sites-enabled/000-default:1)
