The address does not look quite right based on the documentation.

Using the Adobe Update Server Setup Tool (AUSST)

The root folder is the file-system location on your in-house update server where updates from the Adobe update server are stored. The root folder location must map to a valid HTTP URL.

Note:

Ensure that the root folder lies within the access of the server root location so that update content can be served by the web server.

As an example, suppose:

• The root update folder on your web server is at the file-system location /serverroot/updates/
• The web server's URL is http://serverabc.example.com:80
• Within your web server, you set up the in-house update server at
  http://serverabc.example.com:80/Adobe/CS

In this case (which we will use as an example throughout this document), the root folder location is
--root="/serverroot/updates/Adobe/CS"

For this example, the command to run the updates will be:
AdobeUpdateServerSetupTool --root="/serverroot/updates/Adobe/CS" --fresh
