The elastic search master, data and client have stopped communicating with each other and we see NodeDisconnectedException and connection timeout errors on 9300 port
It could be related to a network issue in your Kubernetes cluster but we need more information to help you:
- Kubernetes cluster version, ECK version
- GKE or on-premise cluster? Number of k8s nodes?
- YAML manifest used to deployed the Elastic resources
- Elasticsearch logs
- Have any k8s nodes been restarted?
