I have deployed ECK and BANZAI logging on AKS, then trying sent logs to elasticsearch via fluentd.  
No index have found on the Kibana discovery, I deployed a CentOS pod and verified its HTTP connectivity. But empty responded as follows.

```auto
    sh-4.2# curl -v http://my-elasticsearch-es-http.elastic-system.svc.cluster.local:9200
    * About to connect() to my-elasticsearch-es-http.elastic-system.svc.cluster.local port 9200 (#0)
    * Trying 10.0.85.166...
    * Connected to my-elasticsearch-es-http.elastic-system.svc.cluster.local (10.0.85.166) port 9200 (#0)

    * Connection #0 to host my-elasticsearch-es-http.elastic-system.svc.cluster.local left intact
    curl: (52) Empty reply from server
    sh-4.2#

```

On the other hands, I had deployed elasticsearch via helm provided by Rancher. At the time the elasticsearch responded properly, and Kibana showed an index from fluentd via BANZAI flow.

```auto
    sh-4.2# curl -v http://elasticsearch-master.my-efk-p-988c4.svc.cluster.local:9200
    * About to connect() to elasticsearch-master.my-efk-p-988c4.svc.cluster.local port 9200 (#0)

I am wondering what I am missing. Anyone, please give me what I should do in the ECK case ?

ECK defaults to deploying Elasticsearch with TLS enabled. Have you tried doing a request using `https` instead of `http`?

Here is the documentation to disable TLS: [TLS certificates | Elastic Cloud on Kubernetes [1.4] | Elastic](https://www.elastic.co/guide/en/cloud-on-k8s/1.4/k8s-tls-certificates.html#k8s-disable-tls).
