```
transportClient = transportClient.addTransportAddress(new InetSocketTransportAddress("localhost", 9200));

```

It's the HTTP protocol that uses port 9200. The transport protocol uses 9300. See [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html).

I don't understand what you're saying. Use port 9300, not 9200.
