Could not connect to rabbitmq broker via nodejs client

Question

I am using amqplib to create amqp clients. it works fine when running on localhost, but when I change it to the server's IP address 192.168.1.44, I get an error that indicates the conn object is undefined.

this is the client's code

var amqp = require('amqplib/callback_api');
amqp.connect('amqp://guest:[email protected]:5672', function(err, conn) { 
    conn.createChannel(function(err, ch) {
    var q = 'hello';
    ch.assertQueue(q, {durable: false});
    console.log(" [*] Waiting for messages in %s. To exit press CTRL+C", q);
    ch.consume(q, function(msg) {
    console.log(" [x] Received %s", msg.content.toString());
    }, {noAck: true});
  });
});

and this is the error message

/home/pi/Desktop/mqtt_example/receive.js:14
conn.createChannel(function(err, ch) {
    ^

TypeError: Cannot read property 'createChannel' of undefined

I fixed it by creating a new user on the rabbitmq broker. the guest user works only with localhost. for more details see https://stackoverflow.com/a/26820152/7236105.
