I'm running Service Desk Plus 9.3 Build 9333 and would like our Tech's to be able to access the service desk out on the field with there mobile.

We have service desk sitting behind a firewall & netscaler which is forwarding on requests for our service desk on port 443.

Visiting our site externally works fine ( https://servicedesk.example.com) on both mobile and computer.

The iPhone app works about 70% but some things we try to do like create a new request it pops up a 503 error. The Android app can't sign in at all and bring up's another 503 error. (Request Failed: service unavailable 503). Both apps work perfectly fine when on our corporate network with wifi.

I'm guessing that maybe there are some extra ports required for this to work though our firewall? I've been told by a manage engine tech that the apps are only suppose to work internally but this isn't very helpful for us.
