Personal hosting of Corona Cloud

I have my app deployed as per the setup instructions, but I am still having a problem communicating through my app.

Testing with Curl posts I can communicate and get the right responses like so;

C:\Users\Phil>curl --user Secret_:Access_key

 -X POST -d “login=phil@email.com&password=password”

http://myUrl/user_sessions/user_login.json

But when I try to do this through my app, its not working, If anyone  on the forum here has been through this process, could they tell me if I might have overlooked something

Best regards,

Philip
