UnauthorizedHttpException represents an "Unauthorized" HTTP exception with status code 401.

Use this exception to indicate that a client needs to authenticate via WWW-Authenticate header to perform the requested action.

If the client is already authenticated and is simply not allowed to perform the action, consider using a 403 yii\web\ForbiddenHttpException or 404 yii\web\NotFoundHttpException instead.
