The site has redirected too many times, how to solve?

Question

Yii

Hello! I'm using advanced version of yii2 and /admin has an admin login form. And I added the admin column with the values ​​0 and 1 in the user table. Now I

put the following check in the controller

public function actionIndex()
    {
        if (Yii::$app->user->isGuest || Yii::$app->user->identity->admin!=1) {
            return $this->redirect('/admin/site/login');
        }
        return $this->render('index');
    }

If I enter my username and password correctly when logging in. but this user has admin=0 then I come across this page: Page not available The site abc redirected too many times.
Delete cookies..
ERR_TOO_MANY_REDIRECTS

Only after clearing the cache can I enter my password and login back, how can I solve this? From what redirection is done many times?
