Hello Elastic Team. My name is Kanagat. I am trying configurate connection to Elk node from java by transport client.But i get exception: noNodesAvailable. next my ELK configuration running on server with name XXX: elasticsearch-5.0.2] cat ./config/elasticsearch.yml |grep -v "#" |grep -v "^" cluster.name: eventhandler-test-db node.name: node-3 node.master: true node.data: true path.logs: /data/nugusbayev\_repo/logs/elasticsearch/node3 network.publish\_host: SERVER\_NAME network.bind\_host: 0.0.0.0 discovery.zen.ping.unicast.hosts: ["127.0.0.1", "localhost","SERVER\_NAME"] curl localhost:9200 { "name" : "node-3", "cluster\_name" : "eventhandler-test-db", "cluster\_uuid" : "xb38NQ14SNuyh1eUKA0LbA", "version" : { "number" : "5.0.2", "build\_hash" : "f6b4951", "build\_date" : "2016-11-24T10:07:18.101Z", "build\_snapshot" : false, "lucene\_version" : "6.2.1" }, "tagline" : "You Know, for Search" } SERVER\_NAME:9200 this url permitted(accesed) from any PC in our network. Then i tried use in java project Settings settings = Settings.builder().put("cluster.name", "eventhandler-test-db").build(); TransportClient client = new PreBuiltTransportClient(settings); client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("SERVER\_NAME"), 9300)); System.out.println("QQQ" + client.connectedNodes()); But client not return any nodes. Can you help me what's wrong in my configuration? In addition i add the screen of used libraries. ![](https://us1.discourse-cdn.com/elastic/original/2X/6/62584b97426074d73bd5351b3699035f4ded353d.JPG) ---

Hey, try to also configure the cluster name in your transport client settings. See [configuring the transport client](https://www.elastic.co/guide/en/elasticsearch/client/java-api/5.0/transport-client.html) --Alex ---

Alex, thanks you. But i configured by that instructions. It didn't work. Settings settings = Settings.builder().put("[cluster.name](http://cluster.name)", "eventhandler-test-db").build(); TransportClient client = new PreBuiltTransportClient(settings); client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("SERVER\_NAME"), 9300)); System.out.println("QQQ" + client.connectedNodes()); ---

Hey, sorry I missed that - didnt have any coffee yet. Can you configure the settings `logger.level` to `debug` or `trace` on the `TransportClient`, try again and paste the output? --Alex ---

Hey, you need to put this into the settings of the transportclient, not anywhere on the server. --Alex ---

I set next configuration: Settings settings = Settings.builder().put("[cluster.name](http://cluster.name)", "first").put("logger.org.elasticsearch.transport.TransportService.tracer", "TRACE") .build(); is it correct?

after increas the log level, i saw problem with no class found: then i added netty handler -4.1.6. Then i got message from my last reply. After replace, nodes is now available. ---
