We are using Transport Client to connect to elastic search cluster with 6 nodes on aws. It is taking 3 minutes to connect. Can anyone help with the same ? Following is code snippet.

```
             Settings settings = Settings.builder().put("cluster.name", clusterName).put("client.transport.sniff", true).build();
	TransportAddress[] nodes = new InetSocketTransportAddress[addresses.length];
	for (int idx = 0; idx < nodes.length; idx++) {
			nodes[idx] = new InetSocketTransportAddress(InetAddress.getByName(addresses[idx]), port);
	}
	client = new PreBuiltTransportClient(settings).addTransportAddresses(nodes);

```
