For those interested in what is actually going on:
The Developers Console uses the Cloud Datastore API to access your project's Datastore. The current version of the Cloud Datastore API (v1beta2) uses a special version on your App Engine application (ah-builtin-datastoreservice) in order to serve this API. Unfortunately, sometimes when you first enable the Cloud Datastore API the deployment of this version fails.
We are currently working to remove this layer of the serving stack for the next version of the Cloud Datastore API.
EDIT: Cloud Console now uses Cloud Datastore API v1beta3, so disabling then re-enabling likely will not solve any connection issues.
