For future viewers, this error occurs when the Firebase SDK is unable to reach the Cloud Firestore service for a variety of reasons. We've since moved from Beta to General Availability for the service and SDKs and made several improvements since this was first asked.

A prime reason for this error is network connectivity where we cannot get a response from the service in a reasonable timeframe and then revert to offline mode (if enabled).

Another possible reason in Javascript libraries/frameworks are messing with functionality we rely upon in a now compatible way.

If you continue to encounter this issue and don't believe it's network connectivity relate, post a question on our discussion group or as a Github issue against the relevant client library.
