I am trying to setup 2 elasticsearch nodes in same ip, same cluster name, different node names, and different ports. I made 2 directories to put elasticsearch.yml and logging.yml, to launch 2 instances.

My configuration files are like below

config file 1

```
cluster.name: my_cluster_name
node.name: my_node_name
node.master: true
bootstrap.mlockall: true
network.host: 192.168.2.2
http.port: 9200
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["192.168.2.2:9200","192.168.2.2:9201"]
discovery.zen.minimum_master_nodes: 1

```

config file 2

```
cluster.name: my_cluster_name
node.name: my_node_name_2
node.master: false
node.data: true
bootstrap.mlockall: true
network.host: 192.168.2.2
http.port: 9201
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["192.168.2.2:9200","192.168.2.2:9201"]
discovery.zen.minimum_master_nodes: 1

```

I am getting the error

```
[WARN][discovery.zen.ping.unicast] [my_node_name_2] failed to send ping to [{#zen_unicast_1#}{192.168.2.2}{192.168.2.2:9200}]

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
        at java.lang.Thread.run(Thread.java:745)

```

How can I fix this?

Wrong ports. Use:

```
discovery.zen.ping.unicast.hosts: ["192.168.15.120:9300","192.168.15.120:9301"]
```

I'm still giving you the same answer.

Change with:

```
discovery.zen.ping.unicast.hosts: ["192.168.15.120:9300","192.168.15.120:9301"]
```

Hi,  
could you tell me from where the IP: **192.168.15.120** and ports **9300** and **9301** came from?  
Thanks.

I did not noticed that you changed the IP from your original post.  
For sure don't use the REST ports (9200) but transport ones (9300).
