Custom Social Connection and authorizing an application

[shicholas]

Once again, answered my own question.

The error was because of a rule I set up! D’oh!

How to Add an Authorized Application to a User?

I don’t think this is causing the error you are getting. If the grant was deleted or the consent was never given, the user should be prompted for it. Is it possible that you have a rule throwing an “Access denied” error under certain circumstances?
