Rail Deployment Using nginx & unicorn: 403 Prohibited Error

I just installed VPS (Centos 6.3) and deployed my application using capistrano. VPS runs nginx and unicorn. When visiting the server, I get 403 Forbidden error: this line appears in /var/log/nginx/error.log:

*5 directory index of "/var/www/current/public/" is forbidden, client: xxxxx,   server: xxx, request: "GET / HTTP/1.1", host: "xxxx"

However, if I add index.html to my rails application. / public, everything will work without problems. This makes me think that routes do not work.

I also set permissions for all / var / www folders using chmod -R 755 * (probably not a good idea in the end, but wanted to eliminate this as a source of error). Is there any other way to debug this in more detail (the error.log file tells me nothing)?

Any help is greatly appreciated.

This is my routes.rb file (everything works locally in development)

MyTest::Application.routes.draw do

  root :to => 'welcome#index'
end

nginx.conf:

upstream unicorn {
  server unix:/tmp/unicorn.blog.sock fail_timeout=0;
}

server {
  listen 80 default deferred;
  # server_name example.com;
  root /var/www/current/public;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

    proxy_set_header Host $http_host;
    proxy_redirect off;

  }
