Elastic workloads deployed in GCP stopped working with connection timeout errors

The elastic search master, data and client have stopped communicating with each other and we see NodeDisconnectedException and connection timeout errors on 9300 port

Hello Amirtha,

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?
