No POST from facebook using real-time updates in Rails, Heroku and Koala

This question is an extended version of Facebook. Updated in real time does not call our servers , which seems dead. In addition, Realtime updates the internal server error on Heroku using Koala , it does not help, because I subscribe to the heroku console, as pjaspers suggested.

I have an application ( ruby 1.9.2p290and Rails 3.1.3) that connects to facebook to get the data from the current user. Everything works fine with koala gem (v1.2.1), but I check the fb servers every time users log in. I would like to use real-time updates on facebook, and I read the following:

I installed the system in test mode and successfully deployed to the hero. I can subscribe to the user object and I get a GET request to my server, but there is no POST with updated information received from facebook . If I send POST to my server manually, everything will work.

Additional information: routes.rb

  get '/realtime' => 'realtime#verify'
  post '/realtime' => 'realtime#change'

generating

      realtime GET  /realtime(.:format) {:controller=>"realtime", :action=>"verify"}
               POST /realtime(.:format) {:controller=>"realtime", :action=>"change"}

Controller (breadboard version, only to check if it works):

class RealtimeController < ApplicationController
  def verify
    render :text => params["hub.challenge"]
  end

  def change
    puts params.inspect
    render :nothing => true
  end
end

Subscription from heroku console:

irb(main):004:0> @updates = Koala::Facebook::RealtimeUpdates.new(:app_id => ENV['FACEBOOK_APP_ID'], :secret => ENV['FACEBOOK_APP_SECRET'])
=> #<Koala::Facebook::RealtimeUpdates:0x00000004f5bca8 @app_id="XXXXXXX", @app_access_token="XXXXXXX", @secret="XXXXXXX", @graph_api=#<Koala::Facebook::API:0x00000004a8d7a8 @access_token="XXXXXXX">>

irb(main):005:0> @updates.list_subscriptions
=> [{"object"=>"user", "callback_url"=>"http://blah-blah-0000.herokuapp.com/realtime", "fields"=>["education", "email", "friends", "name", "website", "work"], "active"=>true}]

I do not know what to do next...
