Kibana plugin:elasticsearch

I encountered a problem on Kibana interface where i have a "Statut : Red" with a red warning icon.
"This version of Kibana requires Elasticsearch 2.3.0 on all nodes. I found the following incompatible nodes in your cluster. Elasticsearch v1.2.1".
The things is where i tip : rpm -qa|grep elasticsearch #elasticsearch-2.3.3-1.noarch

When i start the service : sudo service elasticsearch start
Starting elasticsearch : [ OK ]

But when i do a curl -XGET 'http://host:9200' curl : (6) Coulnd't resolve host 'hortonworks.myhost.com'

When i open a browser with the host : 'http://host:9200' i get
{
"status" : 200,
"name" : "Impossible Man",
"version" : {
"number" : "1.2.1", ........
}
}

I don't know how to fix it. Could you please, help me.

(Environnement Sandbox VM from Hortonworks where i try to install an ES-Hadoop connector to do a little POC.)

Thanks.

This is a VM network interface configuration issue.
