Hi Guys,  
I have installed elasticseach and kibana fine on AWS. I can access Kibana from remote server fine.  
However when making API calls using nodejs i get the following error:  
Request error: connect ECONNREFUSED [ip adrress]:9200  
I use the "var elasticsearch = require('elasticsearch'); " to ping the server:  
client.ping({  
requestTimeout: 30000,  
}, function (error) {  
if (error) {  
console.error('elasticsearch cluster is down!');  
} else {  
console.log('All is well');  
}  
});  
Kibana config file is set to host.server" 0.0.0.0  
and config.yml from elastic is set to network.host : 0.0.0.0  
I have also tried network.host: _ec2_

Thanks
