Hello All Problem Resolvers,

We have 3 nodes for elasticsearch 5.5.1. Lets say N1,N2 and N3. All three nodes have been made master node.  
Each of this node is running on single VM. Lets say V1, V2 and V3. So;

1. N1 (Elasticsearch 5.5.1) is running on (virtaul machine) V1.
2. N2 (Elasticsearch 5.5.1) is running on (virtaul machine) V2.
3. N3 (Elasticsearch 5.5.1) is running on (virtaul machine) V3.

# Below is the contents of the elasticsearch.yml file

```
network.host: 192.168.213.25

=============================================================================

Now, the cluster is started and when we try to connect to the Elasticsearch from java client, we get the below exception  
NoNodeAvailableException[**None of the configured nodes are available** : [{#transport#-1}{qVvJFIi5QUSnf0T6cWi0\_g}{192.168.213.25}{192.168.213.25:9300}, {#transport#-2}{4vF9hGcUQoig0tXDIZ6UHA}{192.168.213.19}{192.168.213.19:9300}, {#transport#-3}{eM0M7jcwRjWc7iYPH2ncQw}{192.168.213.24}{192.168.213.24:9300}]]

Someone here, suggest me how to fix this issue.

Regards,  
Maney

Why this?

```auto
network.host: 192.168.213.25
network.bind_host: '0.0.0.0'
transport.bind_host: 0.0.0.0
transport.host: localhost

```

Why not just this?

```auto
network.host: 192.168.213.25

```
