Versions :
Opensearch App version: 2.13.0
Helm Chart version: 2.19.0

Describe the issue:

I am trying to deploy Opensearch 2.13.0 with 3 replicas via Helm chart.
The pods are up and running.
I have also enabled the ingress with tls having valid certificates.
However while I am trying to connect to the cluster using ingress url and I get 502 bad gateway error from nginx

Configuration:
There is no change in any value of the configuration apart from below.

values:
    opensearch:
      resources:
        requests:
          cpu: "6"
          memory: "10Gi"
      extraEnvs:
        - name: OPENSEARCH_INITIAL_ADMIN_PASSWORD
          value: Str0ng@312!
      ingress:
        enabled: true
        tls:
          - hosts:
              -  some url
            secretName: opensearch-tls
        hosts: [
          "some url",
          "Another URL"
        ]

However I see errors like below mentioned in pod logs. Not sure it has relevance here.

Could you please check and let me know why I am unable to connect to opensearch cluster via ingress?

Please note that there are no problems wit ingress-controller deployed in the cluster since it is serving other ingress in the same cluster successfully.

@Stephy Could you share the full values.yml?
According to the error, pods have issues to communicate over SSL at the Transport layer (port 9300). Maybe security plugin configuration is missing.
