I am installing Elastic on GKE with the helm chart here. But after running this command `helm upgrade kibana elastic/kibana --values kibana.yaml` , it runs successfully but the pod gives this error `Readiness probe failed: Error: Got HTTP code 503 but expected a 200` in events.

The values file is shown thus:

```auto
elasticsearchHosts: "https://security-master:9200"

extraEnvs:
  - name: 'ELASTICSEARCH_USERNAME'
    valueFrom:
      secretKeyRef:
        name: elastic-credentials
        key: username
  - name: 'ELASTICSEARCH_PASSWORD'
    valueFrom:
      secretKeyRef:
        name: elastic-credentials
        key: password
  - name: 'KIBANA_ENCRYPTION_KEY'
    valueFrom:
      secretKeyRef:
        name: kibana
        key: encryptionkey

```

I am wondering what might be the issue - could someone advice on how I could avoid this error entirely, thanks!
