Briefly, this error occurs when Elasticsearch is unable to retrieve the list of nodes from Google Cloud Engine (GCE) for cluster discovery. This could be due to network issues, incorrect configuration, or insufficient permissions. To resolve this, ensure that the GCE API is enabled and accessible, check your discovery settings in Elasticsearch configuration, and verify that the Elasticsearch instance has the necessary permissions to access the GCE API.
