使用芹菜发送多封邮件时出错。引发意外：OSError（0，'Error'）和in do\u handshake self_握手()

Question

我想用芹菜任务将一封邮件异步发送给多个收件人。它的工作速度非常慢，而且还显示错误。请帮我拿这个。在

from celery.registry import tasks
from celery.task import Task
import pyotp
from django.core.mail import EmailMultiAlternatives

class CreateDriveTask(Task):
    def run(self, email_list):
        msg = "hiiiiiiiiii"
        return EmailMultiAlternatives("Welcome",msg,"hardeepjethwani123@gmail.com",email_list).send()
tasks.register(CreateDriveTask)

想以一种没有错误的速度发送邮件吗
