Nginx error: (13: Permission denied) when connecting to upstream)

I am running a rails application with puma, capistrano and nginx on a google computer with ubuntu 14.04 LTS.

I have nginx working on an external IP. And when I visit it, I get two nginx errors in the log:

2016/02/03 11:58:07 [info] 19754#0: *73 client closed connection while waiting for request, client: ###.##.##.###, server: 0.0.0.0:443

2016/02/03 11:58:07 [crit] 19754#0: *74 connect() to unix:///home/my-user-name/apps/my-web-app/shared/tmp/sockets/my-web-app-puma.sock failed (13: Permission denied) while connecting to upstream, client: ###.##.##.###, server: , 
request: "GET / HTTP/1.1", upstream: "http://unix:///home/my-user-name/apps/my-web-app/shared/tmp/sockets/my-web-app-puma.sock:/", host: "###.###.###.###"

Note: last ###. ###. ###. ### is the external IP address of the Google Computing Virtual Machine that the code is working on. I believe the first two IPs are my home IP.

I tried: setsebool httpd_can_network_connect onas suggested here: (13: Permission denied) when connecting to the upstream: [nginx] And it came back: setsebool: SELinux is disabled.But the problem persists.

I looked (13: Permission denied) when connecting to the upstream: [nginx] , but it seems to be especially important for thisuwsgi

Here is my nginx.conf

upstream puma {
  server unix:///home/my-user-name/apps/my-web-app/shared/tmp/sockets/my-web-app-puma.sock;
}
server {
  listen 80 default_server deferred;
  listen 443 ssl;
  # server_name example.com;
  ssl_certificate /etc/ssl/my-web-app/my-web-app.com.chained.crt;

  }

    proxy_set_header Host $http_host;

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

I start nginx with sudo service nginx restart Then I start puma with RACK_ENV=production bundle exec puma -p 3000, and it returns:

Puma starting in single mode...
* Version 2.14.0 (ruby 2.1.7-p400), codename: Fuchsia Friday
* Min threads: 0, max threads: 16
* Environment: production
* Listening on tcp://0.0.0.0:3000
Use Ctrl-C to stop

EDIT 1

It has been suggested that I run puma on unix and not tcp 3000 so that it matches nginx

I tried running puma on unix using the command:

RACK_ENV=production bundle exec puma -d -b unix:///tmp/my-web-app.sock --pidfile /tmp/puma.pid

which gave:

Puma starting in single mode...
* Version 2.14.0 (ruby 2.1.7-p400), codename: Fuchsia Friday
* Min threads: 0, max threads: 16
* Environment: production
* Daemonizing...

It reads the text above, but it does not linger, the command line appears again immediately, despite the "..." at the end.
