I am currently working on deploying Elasticsearch in a Kubernetes environment using a Helm chart. The pods are being created and are running without issues. However, I am encountering a problem connecting to the Elasticsearch service from a different Python service. The connection attempt results in the following error:

elastic_transport.TlsError: TLS error caused by: TlsError(TLS error caused by: SSLError([SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1006)))

my chart looks like

- name: elasticsearch
  version: 8.5.1
  repository: https://helm.elastic.co

pods seems to be running fine

elasticsearch-master-0                          2/2     Running     0             92m
elasticsearch-master-1                          2/2     Running     0             92m
elasticsearch-master-2                          2/2     Running     0             92m

able to curl the URL by bypassing the verification

curl -k -u elastic https://elasticsearch-master-headless:9200
Enter host password for user 'elastic':
{
  "name" : "elasticsearch-master-2",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "id",
  "version" : {
    "number" : "8.5.1",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "c1310c45fc534583afe2c1c03046491efba2bba2",
    "build_date" : "2022-11-09T21:02:20.169855900Z",
    "build_snapshot" : false,
    "lucene_version" : "9.4.1",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

within the same pod.
but getting

curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to elasticsearch-master-headless:9200 

error from different pod in the same cluster.

Any help would be appreciated, please ask for more details if needed.
