Mobile App not working: Invalid API key

Hello,
I am having trouble getting the Mobile App to work with our environment. Every time I try to log in to either the Admin server or one of the Managed servers on port 8443, I get the following error: "Invalid APIKey!Please relogin"

Can anyone offer any assistance? Do I need to enable/modify anything in my conf files to get this feature working?

Using:
Application Manager Enterprise Ed. build 11520
Application Manager App for Android v1.2 on Samsung SIII running Android 4.3 (JellyBean)
                New to ADManager Plus?
