ElasticSearch with NEST in Kubernetes - asp.net-core

Question

I'm learning Kubernetes and trying to deploy ElasticSearch & Kibana. And in ElasticSearch v8. https is a default.
https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/connecting-to-elasticsearch-v8.html
I tried to Index a document like this
var settings = new ConnectionSettings(new Uri("https://localhost:9200"))
.BasicAuthentication("elastic", "0fjaNokbmHSeS4kXeFV")
.DefaultIndex("people")
.RequestTimeout(TimeSpan.FromSeconds(300));
var client = new ElasticClient(settings);
var person = new Person
{
Id = 1,
FirstName = "Abc",
LastName = "Abc"
};
var indexResponse = client.IndexDocument(person);
if (!indexResponse.IsValid)
{
var debugInfo = indexResponse.DebugInformation;
var error = indexResponse.OriginalException;
}
But it does not work. Even I can browse https://localhost:9200 with this credentials elastic/0fjaNokbmHSeS4kXeFV
I tried to add https for my ingress and call the service to IndexDocument but it also did not work.
Has anyone faced this issue and could you please help me to make this run?
