Hi,  
I am using nginx to protect the elasticsearch. When trying to access elasticsearch in client js. Its throwing Unable to revive connection: http://ubuntulocal:80:9200/ error.

My question is how to connect the elasticsearch using client js behind the nginx proxy ?

node js code

var elasticsearch = require('elasticsearch');  
var host = [  
{  
host: '[http://ubunutlocal:80](http://ubunutlocal:80)',  
auth: 'root:root'  
}]

var client = new elasticsearch.Client({  
host: host  
});

client.search({  
index : 'bank'  
// undocumented params are appended to the query string  
//hello: "elasticsearch"  
}, function (error , response) {  
if (error) {  
console.error('elasticsearch cluster is down!' , error);  
} else {  
console.log('All is well' , response);  
}  
});

Error log

That doesn't look like a valid URL.

Are you proxying from 9200 to 80?

Yes I'm using nginx proxy and trying to connect to host: '[http://ubunutlocal:80](http://ubunutlocal:80)', url only

Nginx configuration

server {  
listen 80;  
server\_name guidanzlocal;  
location / {  
rewrite ^/(.\*) /$1 break;  
proxy\_ignore\_client\_abort on;  
proxy\_pass [http://localhost:9200](http://localhost:9200);  
proxy\_redirect [http://localhost:9200](http://localhost:9200) [http://guidanzlocal/;](http://guidanzlocal/;)  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
proxy\_set\_header Host $http\_host;  
auth\_basic "Elasticsearch Authentication";  
auth\_basic\_user\_file /etc/elasticsearch/user.pwd;  
}  
}
