SSL с Rails 3.1: config.force_ssl = true не работает в режиме разработки

Я запускаю rails 3.1 в режиме разработки на Ubuntu с sqlite. Сервер rails работает на порту 3000, и у меня nginx настроен на порты proxy_pass 80 и 443 на порт 3000. когда я помещаю config.force_ssl = true в свой Application.rb и перезапускаю сервер rails, Я получаю сообщение об ошибке, которое выглядит примерно так:

    Secure Connection Failed
    An error occurred during a connection to localhost:3000.

    SSL received a record that exceeded the maximum permissible length.

    (Error code: ssl_error_rx_record_too_long)

    The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
    Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.

Когда я снова меняю его на config.force_ssl = false и перезапускаю сервер rails, я все равно получаю сообщение об ошибке [2011-12-30 09 : 48: 02] ERROR bad URI 9W \ x0Fe���h = 9�� ݔ | � # ��) � / 6 \ x00 \ x00H \ x00�� '. в консоли рельсов. Это исчезнет, ​​и все вернется в нормальное состояние, если я также очищу кеш браузера. Но как заставить force_ssl = true работать?

Вот часть моего Application.rb:

    module Regi
      class Application < Rails::Application
        # Settings in config/environments/* take precedence over those specified here.
        # Application configuration should go into files in config/initializers
        # -- all .rb files in that directory are automatically loaded.
        config.generators do |g|
          g.template_engine :haml
        end
        config.force_ssl = true
      end
    end         

А вот мой / etc / nginx / sites-enabled / default:

server {
    #listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6

    root /usr/share/nginx/www;
    index index.html index.htm;

    # Make site accessible from http://localhost/
    server_name localhost;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to index.html
            proxy_pass      http://localhost:3000;  
            try_files $uri $uri/ /index.html;
    }
