Yii::$app->user->isGuest is always true after login in Yii2. What could be the problem?

Question

Yii

I just started to deal with Yii and I am doing registration with authorization through MySQL.
Registration somehow works, but with the authorization of the problem.
In LoginForm::login(), authorization seems to work fine and in Yii::$app->user there is info about the current user, but Yii::$app->user->isGuest is always true in view is always true and in session too empty.
LoginForm.php

<?php

 * LoginForm is the model behind the login form.

            // rememberMe must be a boolean value
            ['rememberMe', 'boolean'],
            // password is validated by validatePassword()
            ['pass', 'validatePassword'],
        ];
    }

Web.php contains the following settings:

'user' => [
            'identityClass' => 'app\models\User',
            'enableAutoLogin' => true,
        ],

The session is also empty. Server sessions seem to be working.
What could be the problem?
Maybe something wrong with the base?
User table structure:

CREATE TABLE IF NOT EXISTS `user` (
`id` int(11) NOT NULL,
  `created_at` int(11) NOT NULL,
  `login` varchar(255) NOT NULL,
  `auth_key` varchar(32) DEFAULT NULL,
  `email_confirm_token` varchar(255) DEFAULT NULL,
  `pass` varchar(255) NOT NULL,
  `password_reset_token` varchar(255) DEFAULT NULL,
  `email` varchar(255) NOT NULL,
  `rights` tinyint(1) NOT NULL,
  `active` tinyint(1) NOT NULL,
  `status` smallint(6) NOT NULL
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 ;

Yii::$app->user->isGuest is always true because your user is not logged in. Why I didn’t log in is another question that you can only solve by debugging your application - see yii logs, enable error_reporting (if it is not enabled)
