Hi, I am trying to use Java Client to connect to my [elastic.co](http://elastic.co) cloud instance. Here is my code, I am getting NoNodeAvailableException. Let me know if I am missing some thing. Appreciate any help. Code: try { // Elastic Endpoint: [https://3bc1590ea5e7ea7fcb7adc416f951b59.us-east-1.aws.found.io:9243](https://3bc1590ea5e7ea7fcb7adc416f951b59.us-east-1.aws.found.io:9243) ``` String clusterName= "autospecs-drawings-dev"; String esHost = "3bc1590ea5e7ea7fcb7adc416f951b59.us-east-1.aws.found.io"; int esPort = 9243; this.transportAddress = new InetSocketTransportAddress(InetAddress.getByName(esHost), esPort); Settings settings = Settings.builder() .put("cluster.name", clusterName). put("logger.org.elasticsearch.transport.TransportService.tracer", "TRACE"). build(); this.client = new PreBuiltTransportClient(settings).addTransportAddress(transportAddress); SearchResponse sr = client.prepareSearch("autospecs-drawings-0").get(); long numHits = sr.getHits().getTotalHits(); System.out.println("Number of hits is " + numHits); } catch (Exception e) { //e.printStackTrace(); // TODO Auto-generated catch block esLogger.error("Exception during getting transportAddress", e); } ``` Exception is this. 15:55:13.640 [main] ERROR - Exception during getting transportAddress org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{1NmEyI9ySICMCg-AuluqMA}{[3bc1590ea5e7ea7fcb7adc416f951b59.us-east-1.aws.found.io](http://3bc1590ea5e7ea7fcb7adc416f951b59.us-east-1.aws.found.io)}{54.197.250.163:9243}] at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:347) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:245) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.client.transport.TransportProxyClient.execute(TransportProxyClient.java:59) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.client.transport.TransportClient.doExecute(TransportClient.java:363) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:408) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:80) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:54) ~[elasticsearch-5.5.0.jar:5.5.0] at org.elasticsearch.action.ActionRequestBuilder.get(ActionRequestBuilder.java:62) ~[elasticsearch-5.5.0.jar:5.5.0] at com.pype.autospecs.util.ESUtil.(ESUtil.java:61) [bin/:?] at com.pype.autospecs.util.ESUtil.(ESUtil.java:28) [bin/:?] ---

I tried, but no luck. I get the same exception. Should I give username/password (elastic/) which [cloud.elastic.co](http://cloud.elastic.co) has given me during sign up some where?? ---

Hare is an example from the docs: [https://www.elastic.co/guide/en/cloud/current/security.html#security-transport](https://www.elastic.co/guide/en/cloud/current/security.html#security-transport) ---

Hi Christian, It looks too complicated to take that code. Also, shield is part of XPack as I have read some where. Would anyone have a readymade Java client code that connects/queries the elastic cloud node? ---

What about it is too complicated? It shows the headings and settings that need to be set in order to be able to connect to Elastic Cloud. ---

Hello Christian, I am using 5.x client. When I use shield.user it says, unknown setting. On the other hand, if I use xpack.security.user, its giving same error. So, for 5.5 client, what is the setting property for given user name and password. I am able to connect using Curl command by giving -u option with username:passwd ---

Just realised that the example in the docs is for ES 2.x. There is however also a link to a 5.x example available on the page which it looks like you have found: [https://github.com/elastic/found-shield-example/blob/5.x/src/main/java/org/elasticsearch/cloud/transport/example/TransportExample.java](https://github.com/elastic/found-shield-example/blob/5.x/src/main/java/org/elasticsearch/cloud/transport/example/TransportExample.java) ---
