Redis Heroku Node.JS Connection Refused

Question

I'm working through a CodeSchool "Soup to Bits" screencast, deploying a simple node.js + redis app to Heroku, and what they've got in the screencast doesn't work for me. Simply trying to get the app to connect to redis using redistogo. Here is the code I'm using, and below the error:

// Redis connection
var redis = require('redis');
if (process.env.REDISTOGO_URL) {
    // production
    var rtg = require("url").parse(process.env.REDISTOGO_URL);
    var client = redis.createClient(rtg.port, rtg.hostname);
    client.auth(rtg.auth.split(":")[1]);
} else {
    // development
    var client = redis.createClient();
    client.select((process.env.NODE_ENV || 'development').length);
}

Error message:

Can anyone see what I'm missing?

Ha, well this is a first. The issue was that I had not declared a variable with Heroku – my credit card.

Needed to enter my CC to add Redis To Go module.
