Flask Mail Exception

Question

Я оформляю заказ 6b(книга "Flask Web Development", глава 6 "Почта") и хочу отправить электронное письмо на тестирование. Но это вызвало исключение. Я использую виртуальную машину (CentOS 7). Исключение следующее:

(venv)➜  flasky git:(09d4ff0) ✗ python hello.py runserver --host 0.0.0.0
 * Running on http://0.0.0.0:5000/

Я использую локальный IP, но я могу подключиться к Интернету. Я изменил некоторые конфигурации: почта, порт, имя пользователя, пароль. Привет.py как поток:

Я не могу справиться с этой проблемой.

Я считаю, что вам стоит использовать SSL.

      app.config['MAIL_USE_SSL'] = True

также вы можете попробовать удалить TLS из своей конфигурации
