Hi!  
I'm trying to connect to my Elasticsearch node from Java.  
I have this code :

```auto
    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
            credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("name", "pass"));

            Path trustStorePath = Paths.get("/home/name/certCA.p12");
            KeyStore truststore = KeyStore.getInstance("pkcs12");

            try (InputStream is = Files.newInputStream(trustStorePath)) {
                truststore.load(is, null);
            }

            SSLContextBuilder sslBuilder = SSLContexts.custom().loadTrustMaterial(truststore, null);
            final SSLContext sslContext = sslBuilder.build();

            RestHighLevelClient client = new RestHighLevelClient(
                    RestClient.builder(
                            new HttpHost("10.10.10.10", 9200, "https")).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {

                        public HttpAsyncClientBuilder customizeHttpClient(
                                final HttpAsyncClientBuilder httpAsyncClientBuilder) {

                            return httpAsyncClientBuilder.setDefaultCredentialsProvider(credentialsProvider).setSSLContext(sslContext);

                        }

                    })

            );
            if(client.ping(RequestOptions.DEFAULT)){
                System.out.println("Connected");
            }

```

After I run it I get error with connection is closed.  
Any idea?  
Thank you!
