Ruby on Rails ActionCable and Redis config using Passenger and Nginx

My ActionCable setup works perfectly in the development environment but it fails in production. For the server I am using Nginx and Phussion Passenger to manage my app.

I believe the issue lies within Redis configuration, my config/cable.yml file looks like this

production:
  adapter: redis
  url: redis://lordwaiter.com:6379

local: &local
  adapter: redis
  url: redis://localhost:6379

development: *local
test: *local

I have followed this guide for this implementation

Integrating Action Cable with Passenger + Nginx In the guide the example url for the redis is redis://redis.example.com:6379 so I tried changing mine to redis://redis.lordwaiter.com:6379 that didn't work as well.

My current config throws this error

Redis::CannotConnectError: Error connecting to Redis

I tried placing localhost instead my hostname like redis://localhost:6379 This time my request was handled without throwing any exceptions but I didn't receive any broadcast in the browser.

I think there needs to be a declaration for the redis url in nginx's virtual host file. I am clueless at this moment and I would highly appreciate any guidance over this.

My Nginx virtual host configuration for my host looks like this

server {

    server_name www.lordwaiter.com lordwaiter.com;
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/lordwaiter/code/public;

    # Turn on Passenger
    passenger_enabled on;
    passenger_ruby /usr/local/rvm/gems/ruby-2.4.0/wrappers/ruby;

    ssl on;
    ssl_certificate /etc/ssl/cert_chain.crt;
    ssl_certificate_key /etc/ssl/private.key;

    location /cable {
        passenger_app_group_name lordwaiter_action_cable;
        passenger_force_max_concurrent_requests_per_process 0;
    }


}
