In the documentation [here](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/java-rest-high-getting-started-initialization.html), they initialize an instance of the client with the following code:

```auto
RestHighLevelClient client = new RestHighLevelClient(
        RestClient.builder(
                new HttpHost("localhost", 9200, "http"),
                new HttpHost("localhost", 9201, "http")));

```

I've configured my ElasticSearch instance on the AWS Console following [these instructions](https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/es-createupdatedomains.html). On the summary page for my newly created instance, there is no port number with the domain.

So my question is, given how I've configured my instance how can I set up and make requests using a RestHighLevelClient if I'm not running the instance locally? I've tried

```auto
 RestHighLevelClient myRestHighLevelClient = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost(ELASTIC_ENDPOINT_DEV)
                )
        );

        GetRequest getRequest = new GetRequest("myIndex", "myType","myID");
        myRestHighLevelClient.get(getRequest);

```

But I am returned with a java.net.ConnectionException: Connection Refused. Please help!

You should ask AWS support for this.

Did you look at [https://www.elastic.co/cloud](https://www.elastic.co/cloud) and [https://aws.amazon.com/marketplace/pp/B01N6YCISK](https://aws.amazon.com/marketplace/pp/B01N6YCISK) ?

Cloud by elastic is the only way to have access to X-Pack. Think about what is there yet like Security, Monitoring, Reporting and what is coming like Canvas, SQL... And 6.3.0 is yet available there!
