Okay, thanks. Seems you missed relevant passages:
So you got exactly what some should get, when browsing to this URL 
ps
Guess it was meant as a simple connection test.
If you browse to a website and the webserver don’t has the document you asked for or has no so called default document defined (default.html oder index.php, etc.) and directory browsing is forbidden, a 404 is shown.
But this means not, that other services like f.e. webservices which are provided by that server, are not working.
