Why does req.isAuthenticated from passposrtjs return false on dev server?

Question

JavaScript

I have a nodejs + express project with passportjs authorization.
If I log in to my localhost (localhost:3000) `req.isAuthenticated` returns true and the user session works correctly.
but if you do the same on the dev server, then the session drops, since req.isAuthenticated will return false.
We tried to look inside the modules themselves, everything seems to be working correctly. The code is the same anyway, the versions of the modules used are the same.
Here is part of the code:
express-session.js

var session = require('express-session'),
express = require('express'),
RedisStore = require('connect-redis')(session);

var date = new Date;
date.setDate(date.getDate() + 30);

module.exports = session({
    secret: 'SECRET',
    resave: true, //don't save session if unmodified
    saveUninitialized: true, // create session until something stored
    expires: date.toUTCString(),
    cookie: {
        secure: false,
        httpOnly : true,
        maxAge : 30 * 60 * 1000 //30 minutes
    },
    rolling: true
});

login.js

exports.post = function (req, res, next) {
passport.authenticate('local', { badRequestMessage: 'Error in your fields' },
    function (err, user, info) {
        if (err) return next(err);
        if (user) {
            req.logIn(user, function (err) {
                if (err) return next(err);
                return res.format({
                    json: function () {
                        res.json({
                            link : '/personal/cabinet/'
                        });
                    }
                });
            });
        } else {
            return res.format({
                html: function () {
                    res.render('auth/login', {
                        error: info.message,
                        title: 'Login'
                    });
                },
                json: function () {
                    res.json(info);
                }
            });
        }
    }
  )(req, res, next);
};

passportjs

var passport = require('passport'),
localStrategy = require('./strategy/localStrategy'),
models = require('models'),
Author = models.author;

//get user data for session
passport.serializeUser(function (user, done) {
    done(null, user);
});
passport.deserializeUser(function (user, done) {
  Author.findOne({
    where: {
        id: user.id
    }
  }).then(function (user) {
    done(null, user);
  });
});

localStrategy(passport);

module.exports = passport.initialize();

app.js

...
app.use('bodyParserJson');
app.use('bodyParserUrldecoded');
app.use('cookieParser');
app.use(path.join('authPassport', 'session')); //express-session
app.use(path.join('authPassport', 'init')); //pasportjs
app.use(passport.session());

...

Versions: passport: 0.3.2, express-session: 1.13.0, express: 4.13.1, nodejs: 4.2.6
What could be the problem? Where can I see more details? Thank you!

Answer 1

Are you getting the user object in the middleware where do you have req.isAuthenticated?
I can't understand either. The user object is received, which means that all validations were successful.
I receive a cookie, it lies on the client, where it is supposed to lie.
What could it be? Sessions?
