Everyauth - connect with Foursquare

I'm trying to build a Foursquare app and I've selected the Everyauth module to implement the authentication (Connect with Foursquare).

I'm getting the error

Error: Step getAccessToken of `foursquare` module timed out.

after the user allows the app. Here is the code I'm using:

var express = require('express'),
        util = require('util'),
        helper = require('./helper'),
        settings = require('./settings').appSettings,
        everyauth = require('everyauth');

everyauth.foursquare
  .entryPath('/auth/foursquare')
  .callbackPath('/auth/foursquare/callback');

//everyauth.everymodule.moduleTimeout(-1);

everyauth.foursquare
  .appId(settings.appId)
  .appSecret(settings.appSecret)
  .findOrCreateUser( function (session, accessToken, accessTokenExtra, foursquareUserMetadata) {
    util.inspect(arguments);
    return {};
  })
  .redirectPath('/');

  var app = express.createServer(
      express.bodyParser()
    , express.static(__dirname + "/public")
    , express.favicon()
    , express.cookieParser()
    , express.session({ secret: '*****'})
    , everyauth.middleware()
  );

app.get('/', function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.end('<html><head></head><body><a href="' + helper.getAuthUrl() + '">Connect with Foursquare</a></body></html>');
});

everyauth.helpExpress(app);

app.listen(4040);

My mistake, I was redirecting the users to the app authentication url as described in the Foursquare documentation. It works if I redirect the user to /auth/foursquare/, as everyauth handles the redirect to oauth provider.
