Flask-Mail Google SSL "smtplib.smtpserverdisconconed: соединение неожиданно закрыто" ⇐ Python

[Anonymous]

Итак, теперь, когда я добавил SSL вместо TLS, есть, по крайней мере, некоторый прогресс, но он все еще не работает. Секунды, и я получаю ошибку, которая неожиданно закрыта.from flask import Flask

В чем может быть проблема? Раньше, когда я использовал TLS, ошибка была что -то вроде сервера отказалась подключаться, теперь это так. Порт кажется правильным, 465 для SSL. Mail_username - мой адрес электронной почты, Mail_password - это пароль приложения для недавно созданного приложения в Google «Пароли приложений». Моя учетная запись Google должна быть в порядке, так как я использовал это приложение по электронной почте некоторое время назад.
