Getting net/http: TLS handshake timeout while accessing AWS managed Elasticsearch service

[nsvijay04b1]

Created a container with image abutaha/aws-es-proxy:v1.1 with below args

Args:
      -endpoint=https://vpc-XXXX-logging-tracing-XXXXXXXXXX.eu-west-1.es.amazonaws.com
      -listen=:9200
      -pretty
      -verbose
      -debug

Created another container in same k8s cluster with "curl" in it and did curl
curl http://<aws-es-proxy container IP>:9200/_app/kibana

Instead of giving HTTP success getting error
Get "https://vpc-XXXX-logging-tracing-XXXXXXXXXX.eu-west-1.es.amazonaws.com/_app/kibana": net/http: TLS handshake timeout

If i run curl -k https://vpc-vijay05-logging-tracing-vcyvcp7ulgghot4gu45wgjlm4i.eu-west-1.es.amazonaws.com from the same container, i get response.

  },
  "tagline" : "You Know, for Search"
}

VPC based Elasticsearch access policy is open and the aws-es-proxy container is created in same VPC.

Env :-
K8S: v1.16.8-eks-e16311
docker: 19.3.6
OS: Amazon Linux 2

please advise.
