Ошибка Python IMAP TimeoutError: [WinError 10060]

Question

Я пишу скрипт для получения вложения из электронного письма.В тот момент мой код должен только захватить вложение электронной почты.Я не вижу ничего плохого в своем коде для получения самой новой электронной почты (верхняя часть входящей почты), и мой IMAP настроен для учетной записи.Может кто-нибудь объяснить мне, почему я получаю ошибку.

TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
