Hi, I'm running ELK stack using helm charts through the elastic community operator git repo. My ES is a single node cluster, today morning suddenly the pod failed and unable to bring up and receiving the below from the event. **Readiness probe failed: Waiting for elasticsearch cluster to become ready (request params: "wait\_for\_status=yellow&timeout=1s" ) Cluster is not yet ready (request params: "wait\_for\_status=yellow&timeout=1s" )** I have already added in elasticsearch.yml config the below parameter clusterHealthCheckParams: "wait\_for\_status=yellow&timeout=1s" But still getting the below error. and this from the ES log... `Preformatted text` "timestamp": "2021-05-06T09:09:47,490Z", "level": "WARN", "component": "o.e.l.LicenseService", "cluster.name": "elasticsearch", "node.name": "elasticsearch-master-0", "message": "LICENSE [EXPIRED] ON [WEDNESDAY, APRIL 28, 2021].\n# IF YOU HAVE A NEW LICENSE, PLEASE UPDATE IT.
