Faye doesn't work properly

Question

I'm writing a simple real-time chat, so I decided to use web-sockets. I used gem 'faye-rails'. Web console shows that it works POST http://khersonchat.herokuapp.com/faye [HTTP/1.1 200 OK 170ms] but when I send a message there's an error: While loading the page connection ws://khersonchat.herokuapp.com/faye was broken(translated from Russian). So when I send a message, the whole page still reloads, and I need to reload a page to see other people's messages sent.

messages_controller.rb:

def create
    respond_to do |format|
        if current_user
            @message = current_user.messages.build(message_params)
            if @message.save
                flash[:success] = 'Message sent'
            else
                flash[:error] = 'Oops, an error :('
            end
            format.html {redirect_to root_path}
            format.js
        else
            format.html {redirect_to root_path}
            format.js {render nothing: true}
        end
    end
end

application.js:

//= require jquery
//= require jquery_ujs
//= require faye
//= require messages
//= require_self
//= require turbolinks

messages.coffee:

window.client = new Faye.Client('/faye')

jQuery ->
    $('#new_message').submit ->
        $(this).find("input[type='submit']").val('Sending...').prop('disabled', true)
    try
        client.unsubscribe('/messages')
    catch
        console?.log "Can't unsubscribe"

    client.subscribe '/messages', (payload) ->
        $('#messages').find('.media-list').append(payload.message) if payload.message

create.js.erb

publisher = client.publish('/messages', {
    message: '<%= j render @message %>'
});

publisher.callback(function() {
     $("#message_body").val('');
     $("#new_message").find("input[type='submit']").val('Send').prop('disabled', false)
});

publisher.errback(function() {
    alert('Oops, an error');
});

important! the chat authenticates via omniauth, using a social network Vkontakte(vk.com), so the version stored in git has the access to localhost

The problem was with Csrf Protection, so the topic continues here
