CloudAQMP with NodeJs and Celery

I'm able to use cloudamqp documentation to connect using Nodejs client as shown in sample code on cloudaqmp's website, but I can't seem to do so using celery in my nodejs application on Heroku. Here is the snippet I'm using to connect in my application where I have defined my CLOUDAMQP_URL variable:

var celery = require('node-celery'),
    client = celery.createClient({
        CELERY_BROKER_URL: (process.env.CLOUDAMQP_URL || 'amqp://guest:guest@localhost:5672//'),
        CELERY_RESULT_BACKEND: 'amqp',
        BROKER_POOL_LIMIT: 1, //Will decrease connection usage
        BROKER_CONNECTION_TIMEOUT: 300, //# May require a long timeout due to Linux DNS timeouts etc
        CELERY_SEND_EVENTS: true 
    });

client.on('error', function(err) {
    console.log("Cannot connect to CLOUDAMQP using celery");
    console.log(err);
});

I am throwing an error in the client.on('error') callback. The error is nondescriptive: Cannot connect to CLOUDAMQP using celery

{ [Error: read ECONNRESET] code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' }

How should I debug this? I could not find an example of how to do this. FYI I have checked that the above syntax works for a local amqp queue (i.e it works on my machine for amqp://guest:guest@localhost:5672//)
