SorceryでのTwitter連携ができません。

Question

SorceryというGemを使ってTwitterと連携・登録したいのですが下記のようなエラーが発生します。下記のコードに問題があるそうです。

OAuth::Unauthorized in OauthsController#oauth

401 Authorization Required

# and after authorizing there back to the callback url.
def oauth
  login_at(params[:provider])
end

def callback

こちらが上記のエラー発生したファイルの全部です。

class OauthsController < ApplicationController
  skip_before_action :require_login, raise: false

  # sends the user on a trip to the provider,
  # and after authorizing there back to the callback url.
  def oauth
    login_at(params[:provider])
  end

  def callback
    provider = params[:provider]
    if @user = login_from(provider)
      redirect_to root_path, :notice => "Logged in from #{provider.titleize}!"
    else
      begin
        @user = create_from(provider)
        # NOTE: this is the place to add '@user.activate!' if you are using user_activation submodule

        reset_session # protect from session fixation attack
        auto_login(@user)
        redirect_to root_path, :notice => "Logged in from #{provider.titleize}!"
      rescue
        redirect_to root_path, :alert => "Failed to login from #{provider.titleize}!"
      end
    end
  end

  #example for Rails 4: add private method below and use "auth_params[:provider]" in place of
  #"params[:provider] above.

  # private
  # def auth_params
  #   params.permit(:code, :provider)
  # end

end

こちらがsorceryの設定ファイルです。

...
Rails.application.config.sorcery.submodules = [:external]

# Here you can configure each submodule's features.
Rails.application.config.sorcery.configure do |config|

 ...

  config.external_providers = [:twitter]

  ...

  # Twitter will not accept any requests nor redirect uri containing localhost,
  # make sure you use 0.0.0.0:3000 to access your app in development
  #
  config.twitter.key = "1B3rI5LuFGz7Niwo0D1hU3AlW"
  config.twitter.secret = "kUcT9xagNqgFzh9lbWP08zNM5QbcQ3agRj0SHXVHd7diya8Rpq"
  config.twitter.callback_url = "http://192.168.33.15:3000/oauth/callback?provider=twitter"
  config.twitter.user_info_mapping = {:email => "screen_name"}

 ...

  # --- user config ---
  config.user_config do |user|

   ...

    # -- external --
    # Class which holds the various external provider data for this user.
    # Default: `nil`
    #
    user.authentications_class = Authentication

    # User's identifier in authentications class.
    # Default: `:user_id`
    #
    # user.authentications_user_id_attribute_name =

    # Provider's identifier in authentications class.
    # Default: `:provider`
    #
    # user.provider_attribute_name =

    # User's external unique identifier in authentications class.
    # Default: `:uid`
    #
    # user.provider_uid_attribute_name =
  end

  # This line must come after the 'user config' block.
  # Define which model authenticates with sorcery.
  config.user_class = 'User'
end

Twitterデベロッパーツールの設定にはCALLBACK_URLも追加してあります。
APIキーも間違っていませんでした。

ふぉなたか原因わかる方いらしましたら教えてください。お願いします
