Connexion avec Steam OpenId avec Steam OmniAuth gem donne erreur "invalid_credentials"

Question

J'essaie d'utiliser la gemme omniauth-steam pour connecter un utilisateur via Steam et récupérer ID64 de l'utilisateur. Je cours Ruby on Rails 5.0.1 en utilisant un serveur sur mon réseau local sportif Apache avec passager. Chaque fois que j'essaie de me connecter à/auth/steam, je suis redirigé vers la page web Steam avec le bouton "Connect" (je suis déjà connecté). Lorsque je clique sur le bouton, je reçois une page d'erreur avec le message "invalid_credentials". Je suis connecté à Steam et peux naviguer sur le site sans problème. D'où vient ce message? Comment puis-je réparer cela? Voici mon code jusqu'à présent.

Omniauth initialiseur:

# config/initializers/omniauth.rb 
Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :steam, Rails.application.secrets.steam_web_api_key 
end 

Controller:

skip_before_filter :verify_authenticity_token, :only => :auth_callback 

def index 
end 

def auth_callback 
    auth = request.env['omniauth.auth'] 
    session[:current_user] = { 
     :nickname => auth.info['nickname'], 
     :image => auth.info['image'], 
     :uid => auth.uid 
    } 
    redirect_to root_url 
end 

Voir:

<p><%= link_to image_tag("http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_large_noborder.png"), '/auth/steam' %></p> 

Routes:

get 'admin/index' 
post 'auth/steam/callback' => 'admin#auth_callback' 

root 'admin#index' 

pile d'erreur:

invalid_credentials

Il se trouve que dans ce cas, il était à cause d'une différence de temps entre le serveur exécutant le script et le serveur de Steam. La date/heure sur mon serveur était plusieurs minutes et dès que j'ai corrigé l'écart de temps, le message d'erreur a disparu et le processus de connexion a réussi.
