Невозможно войти, используя Scrapy

Для справки

Код выполняется правильно, и в пауке нет ошибок. Я думаю, что это связано с сайтом. Могу ли я узнать, чего не хватает и как я могу преодолеть эту проблему. Даже после того, как я пытаюсь войти через браузер, он показывает неверный токен csrf. Нужно ли что-нибудь добавить, дайте мне знать.
