I have the NSD 7.0.1 appliance up and running, and am trying to set up the
Android App on a tablet. Using the tablet I can connect to the web
interface using the DNS name of the NSD server, but when I configure the
Android App with the same credentials, it gives a "Failed to connect"
error. The server firewall is not running.

Am I missing some server side configuration, or what might be the issue?
