Delpi Datasnap Exception in Safecall Method

I am using Delphi XE5 and Datasnap to connect an Android device to a MS SQL server database which is located on a hosted server. The Hosted Server is running the Server application. The application works when I run the server module in the IDE, However when I run it on the Android device I get a message 'Exception in Safecall Method' when it tries to open the Server application on my hosted server via the internet

It was works when I use a desktop pc (on the same local WiFi as the adnroid device), to run the Server Application, the problem seems to be only when I access the Datasnap Server program over the internet
