I noticed you mentioned that the App Engine app and Cloud SQL instance are in the same region, but are they part of the same project?
If they are in the same project, no authorization is needed, otherwise you still need to go to 'Access control' -> 'Authorization' -> 'App Engine authorization' in the instance details and follow the steps to add the App Engine default service account for the App Engine project as an Editor in the Cloud SQL instance project. Even if they're in the same project, you may still have a problem if the App Engine default service account is missing from the 'IAM & Admin' section of the project. If it was deleted, usually you need to recreate the project. However, there's a workaround which you can try <https://code.google.com/p/googleappengine/issues/detail?id=13085> to recover it in the Cloud Console.
