I have setup elasticsearch on one separate server and Logstatsh & Kibana (Both) on one server.  
1st server- ES  
2nd server- Logstatsh and kibana

I have added Elasticsearch.yml  
network.host: 0.0.0.0  
and  
kibana.yml  
server.host: "0.0.0.0"  
elasticsearch.url: "http://\<ES\_Public\_IP\>:9200"

and the problem is my kibana not conneting to elasticsearch  
How can I connet elsaticseach to kibana and logstatsh?

What do you see if you put the above URL in your web browser?

Can you access it from the machine running Kibana? Try

```
curl http://<ES_Public_IP>:9200
nc -n -z <ES_Public_IP> 9200

```

The Kibana can not connect either...

Is ES definitely running? Can you connect to ES locally on the machine where ES runs? Try the same commands with both local and public IP.

Then it's a network issue, firewall blocking ports or something like that.
