Please help me to connect to the elastic cloud from the transport client

```

Code in JAVA Spring BOOT

```
      boolean enableSsl = true;

            .build();

    String hostname = "7c12baf8da6b4c1da553c7557a004844.us-east-1.aws.found.io";
    try {

        System.out.println("CONNECT");
        TransportClient myclient = new PreBuiltTransportClient(settings)
                .addTransportAddress(new TransportAddress(InetAddress.getByName(hostname), 9343));

    }catch (Exception e){
        e.printStackTrace();

First you need to use the same client version as the server. 6.5.4 and not 6.0.0.

Then you need to read: [https://www.elastic.co/guide/en/elasticsearch/reference/6.5/setup-xpack-client.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/setup-xpack-client.html)

That is already added to the pom.xml file 😥 The version is correct or not please

@dadoonet I could see the below item in the documentation

Kindly have a look and guide me to resolve the same

```
 java.lang.IllegalArgumentException: empty text

```

The exception is typically seen when a https request is made to a node that is not using https. If https is desired, please ensure the following setting is in elasticsearch.yml:

```
xpack.security.http.ssl.enabled: true

```

Don't read old documentation. [https://www.elastic.co/guide/en/x-pack/5.4/security-troubleshooting.html](https://www.elastic.co/guide/en/x-pack/5.4/security-troubleshooting.html) is for 5.4.

There is an example of a 6.2 version which I hope is still accurate:

> **[elastic/found-shield-example](https://github.com/elastic/found-shield-example)**
>
> Elastic Cloud Shield Transport Example. Contribute to elastic/found-shield-example development by creating an account on GitHub.

But you should NOT be using the transport client anyway but the REST Client instead.

Thank you very much I could connect with the below code

```
public class ElasticsearchConfig {

@Value("${elasticsearch.host}")
private String host;

@Value("${elasticsearch.port}")
private int port;

@Value("${elasticsearch.username}")
private String userName;

@Value("${elasticsearch.password}")
private String password;

@Bean(destroyMethod = "close")
public RestHighLevelClient client() {

    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(userName, password));

    RestClientBuilder builder = RestClient.builder(new HttpHost(host, port))
            .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));

    RestHighLevelClient client = new RestHighLevelClient(builder);

    return client;

}

```

}
