Error when I try to authenticate through Facebook with omniauth

Question

I followed Ryan Bates Omniauth Part1 railscats http://railscasts.com/episodes/235-omniauth-part-1 . I put twitter and Facebook authentication with their secret numbers and when I try to authenticate through Facebook (auth/facebook) I get this error:

{
   "error": {
      "message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration.",
      "type": "OAuthException"
   }
}

And when I try to authenticate through twitter (auth/twitter) I get this 401 Unauthorized response. I don't know how I can correct it

Thanks I corrected entering http://127.0.0.1:3000 in twitter URL callback field and in facebook my website field. But now when I try to authenticate with facebook I get this error:

OpenSSL::SSL::SSLError

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

How can I solve it? I solved putting OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE in development.rb

That error appears when your server runs on http protocol. You need to add this piece of code in your_project/script/rails before APP_PATH

require 'rubygems'
require 'rails/commands/server'
require 'rack'
require 'webrick'
require 'webrick/https'

module Rails
    class Server < ::Rack::Server
        def default_options
            super.merge({
                :Port => 3000,
                :environment => (ENV['RAILS_ENV'] || "development").dup,
                :daemonize => false,
                :debugger => false,
                :pid => File.expand_path("tmp/pids/server.pid"),
                :config => File.expand_path("config.ru"),
                :SSLEnable => true,
                :SSLVerifyClient => OpenSSL::SSL::VERIFY_NONE,
                :SSLPrivateKey => OpenSSL::PKey::RSA.new(
                       File.open("/path_to_your/privatekey.pem").read),
                :SSLCertificate => OpenSSL::X509::Certificate.new(
                       File.open("/path_to_your/servercert.crt").read),
                :SSLCertName => [["CN", WEBrick::Utils::getservername]]
            })
        end
    end
end

To generate self-signed certificates read this tutorial http://www.akadia.com/services/ssh_test_certificate.html (steps 1 to 4) or this www.tc.umn.edu/~brams006/selfsign.html

After updating your rails script change the url from http://127.0.0.1:3000 to https://127.0.0.1:3000
