NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{IfVRlxsUSDGVyFzl_Rabkg}{10.10.10.109}{10.10.10.109:9300}]]

Question

I've installed elasticsearch 5.0.2(latest version) on my server(10.10.10.109) and trying to create Transport client from java, i'm unable to connect and getting the "NoNodeAvalible exception". I've included the same version of elasticsearch maven dependency in my project. But didn't getting to know where am i going wrong.

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("10.10.10.109"), 9300));

Here is my elasticsearch.yml file

#
        # NOTE: Elasticsearch comes with reasonable defaults for most settings.
        #       Before you set out to tweak and tune the configuration, make sure you
        #       understand what are you trying to accomplish and the consequences.
        #
        # The primary way of configuring a node is via this file. This template lists
        # the most important settings you may want to configure for a production cluster.
        #
        # Please see the documentation for further information on configuration options:
        # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html>
        #
        # ---------------------------------- Cluster -----------------------------------
        #
        # Use a descriptive name for your cluster:
        #
        #cluster.name: my-application
        #
        # ------------------------------------ Node ------------------------------------
        #
        # Use a descriptive name for the node:
        #
        #node.name: node-1
        #
        # Add custom attributes to the node:
        #
        #node.attr.rack: r1
        #
        # ----------------------------------- Paths ------------------------------------
        #
        # Path to directory where to store the data (separate multiple locations by comma):
        #
        #path.data: /path/to/data
        #
        # Path to log files:
        #
        #path.logs: /path/to/logs
        #
        # ----------------------------------- Memory -----------------------------------
        #
        # Lock the memory on startup:
        #
        #bootstrap.memory_lock: true
        #
        # Make sure that the heap size is set to about half the memory available
        # on the system and that the owner of the process is allowed to use this
        # limit.
        #
        # Elasticsearch performs poorly when the system is swapping the memory.
        #
        # ---------------------------------- Network -----------------------------------
        #
        # Set the bind address to a specific IP (IPv4 or IPv6):
        #
        network.host: 10.10.10.109
        #
        # Set a custom port for HTTP:
        #
        #http.port: 9200
        #
        # For more information, see the documentation at:
        # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html>
        #
        # --------------------------------- Discovery ----------------------------------
        #
        # Pass an initial list of hosts to perform discovery when new node is started:
        # The default list of hosts is ["127.0.0.1", "[::1]"]
        #
        #discovery.zen.ping.unicast.hosts: ["host1", "host2"]
        #
        # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
        #
        #discovery.zen.minimum_master_nodes: 3
        #
        # For more information, see the documentation at:
        # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html>
        #
        # ---------------------------------- Gateway -----------------------------------
        #
        # Block initial recovery after a full cluster restart until N nodes are started:
        #
        #gateway.recover_after_nodes: 3
        #
        # For more information, see the documentation at:
        # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html>
        #
        # ---------------------------------- Various -----------------------------------
        #
        # Disable starting multiple nodes on a single system:
        #
        #node.max_local_storage_nodes: 1
        #
        # Require explicit names when deleting indices:
        #
        #action.destructive_requires_name: true

Answer 1

I got the answer, my server firewall was blocking the 9300 port, that is why i'm unable to connect. Thanks.
