I am new to elastic search and I have created a 3 node elastic search cluster in Microsoft Azure using the "Elastic Stack" template. But I am not able to connect to the cluster using connection pool or using a single node connection.

Here's my code:  
var uris = new[]  
{  
new Uri("http://\<\>:9200")  
};

```
            var connectionPool = new SniffingConnectionPool(uris);

            var settings = new ConnectionSettings(connectionPool)
                .SniffOnConnectionFault(false)
                .SniffOnStartup(false)
                .RequestTimeout(TimeSpan.FromSeconds(500))
                .PingTimeout(TimeSpan.FromSeconds(500))
                .MaximumRetries(5)
                .DefaultIndex("people");

            var client = new ElasticClient(settings);

```

It gives me the error:  
FailureReason: PingFailure while attempting PUT on http://\<\>:9200/people/person/1

Any suggestions , what I could be missing?

It looks like your trying to connect to the node through its local IP address rather than through a public IP address.

If you're using **[Elastic's Azure ARM template](https://github.com/elastic/azure-marketplace)** to deploy a cluster, you'll need to deploy either an external load balancer or Application Gateway in order to connect to the cluster from outside of the virtual network;

**If you're deploying through the Azure Marketplace portal** :

**if you're deploying through Azure CLI or PowerShell** :

You can specify the `loadBalancerType` as either `external` for external load balancer or `gateway` for Application Gateway.

You may also find the [blog post on deploying Elasticsearch and Kibana to Azure](https://www.elastic.co/blog/elasticsearch-and-kibana-deployments-on-azure) useful.
