Zend Framework working on Local Server but not on Public Server

Hello all, So I've been working on a php application using the Zend framework, specifically the GData portion. I use it to access Google Spreadsheets and pretty much use a public spreadsheet as a database of information for my app. The app works perfectly fine on my local WAMP server, however after setting up and hosting the app on Servergrove, I get errors and the app won't run. Specifically I get this error:

Uncaught exception 'Zend_Gdata_App_AuthException' with message 'Authentication with Google failed. Reason: BadAuthentication'

Now, I know from the error it's saying that the google account I'm linking to is not authorizing correctly, however, I didn't change any code between testing on my local server and uploading it to Servergrove, so I don't understand why it is failing now. Could anyone possibly point me towards a solution?

EDIT: Solved it! For anyone who might come across the same problem, it turns out that when you use the Zend Gdata framework, you will have to tell google to allow the app to sign into whatever google account you are using in the app.
