Unicorn + Nginx Rails production error

I'm following this tutorial to deploy a RoR app with Capistrano but I'm getting an error in my production server 

[error] 28314#0: *1 connect() to unix:/tmp/unicorn.myapp.sock failed (111: Connection refused) while connecting to upstream, client: xx.xxx.xx.xx, server: , request: "GET / HTTP/1.1", upstream: "http://unix:/tmp/unicorn.myapp.sock:/", host: "myapp.cloudapp.azure.com"

My /etc/nginx/sites-available/default

upstream app {
  # Path to Unicorn SOCK file, as defined previously
  server unix:/tmp/unicorn.myapp.sock fail_timeout=0;
}

server {

  listen 3000;
  server_name localhost;

  root /home/deploy/apps/myapp/current/;

  try_files $uri/index.html $uri @app;

  location @app {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://app;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

I changed the server to many different things, but I get the exact same error, with the same host, server, upstream.

The problem was with Unicorn, somewhere in my Capistrano deploy, it wasn't restarting Unicorn as it should.

Nginx logs indicate that this is an issue with the backend server. After your backend up is up and running. Check:

Once those tests pass, test again through Nginx.
