[BlueOnyx:20147] Web redirect to 444

[Colin Jack]

On all my BX boxes if I put the name of the server into the browser it redirects to the login with port 444
So if I type in  http://server1.domain.com it will then redirect to http://server1.domain.com:444/login.php 
If I type in http://<server ip address> it loads the first vsite include at the bottom of httpd.conf as I would expect.

This is except one server which redirects to the first vsite if I use the url or the IP address. :-/

Looking in httpd.conf shows document root as /var/www/html and this is not commented out.
In that folder is the index.html with the correct redirect.

I should know this, but what am I missing? Apache is obviously not picking up the header on the query?
ServerName is correct in httpd.conf

I should know this but I think I have been looking at it too long! Can't see wood for trees!

Thanks

Colin
