Hi,  
I have a similar issue connecting to elastic cloud. I followed the instructions how to set high-level client.  
The problem i have is "Connection reset by peer". Could you help me with this issue? I tried to search online about how to connect to elastic cloud, but I failed to find any. Thank you.

Code below does work with regular ES node I installed on ami linux image.

Code:  
final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();  
credentialsProvider.setCredentials(AuthScope.ANY,  
new UsernamePasswordCredentials("username", "password"));

```
    RestClientBuilder builder = RestClient.builder(new HttpHost("clusterId.us-east-1.aws.found.io", 9243));
    lowRestClient = builder.build();
    highLevelClient = new RestHighLevelClient(builder);
   CreateIndexRequest request = new CreateIndexRequest("index-abc");
   CreateIndexResponse createIndexResponse = highLevelClient.indices().create(request);

```

Exception in thread "main" java.io.IOException: **Connection reset by peer**  
at org.elasticsearch.client.RestClient$SyncResponseListener.get(RestClient.java:728)  
at org.elasticsearch.client.RestClient.performRequest(RestClient.java:235)

@Mingchih_Lin It would be better to open your own question as it's a different problem.  
Will be easier for other users to find it IMO. Also, would be lovely if you format your code to make it nicer to read. (See [https://discuss.elastic.co/c/elasticsearch](https://discuss.elastic.co/c/elasticsearch))

Anyway, you need probably to change:

```auto
RestClientBuilder builder = RestClient.builder(new HttpHost("clusterId.us-east-1.aws.found.io", 9243));

```

to

```auto
RestClientBuilder builder = RestClient.builder(new HttpHost("clusterId.us-east-1.aws.found.io", 9243, "https"));

```
