Final Step in upgrade to Minimserver 2

[progmanpete]

Hi I have been using Minimserver for a few years and decided that I should purchase and move to Server 2. I have followed the instructions and the Minimserver package is now running on my Synology NAS (DS213J) but whenever I click the Open button to set the path to my music files I get an error saying that the page is not reachable:

Cannot reach this page

•Make sure the web address http://192.168.1.172:9790 is correct

Has anyone seen this error or know a workaround. I have had to put entries into my router NAT table in the past to cover external access but had assumed that this would only need internal access.
