There are no Phusion Passenger(R)-served applications running whose paths begin with '/home/deploy/phjnew'

I'm very new to deployment, and I'm getting this error when I deploy my Rails app to an AWS EC2 instance

There are no Phusion Passenger(R)-served applications running whose paths begin with '/home/deploy/phjnew'.

server {
  listen 80;
  listen [::]:80;

  server_name _;
  root /home/deploy/phjnew/current/public;

  passenger_enabled on;
  passenger_app_env production;

  location /cable {
    passenger_app_group_name phjne_websocket;
    passenger_force_max_concurrent_requests_per_process 0;
  }

  # Allow uploads up to 100MB in size
  client_max_body_size 100m;

  location ~ ^/(assets|packs) {
    expires max;
    gzip_static on;
  }
}

So I got an answer to this on a different question.

When you run this command

sudo less /var/log/nginx/error.log

You'll get an error similar to

copy2013/10/21 17:16:03 [alert] 98687#0: *1 Cannot stat '/Users/phusion/Sites/rack.test/config.ru': Permission denied (errno=13); This error means that the Nginx worker process (PID 99064, running as UID 70) does not have permission to access this file.
