Конфигурация Django SMTP для отправки электронной почты

Я уже настроил электронную почту. Он работал отлично, но через некоторое время он не работает и не отправляет почту. Я не знаю, где возникла проблема. Может ли кто-нибудь помочь мне с этим?

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'myemail'
EMAIL_HOST_PASSWORD = 'mypass'

вот мой код функции электронной почты:

def my_email():
    order = Order.objects.filter(createdAt__gt=Now()-timedelta(minutes=1))
    p = str(settings.BASE_DIR)
    with open(p + '/templates/email.html') as f:
        order_message = f.read()
    for o in order:
        print(o._id)
        email = EmailMultiAlternatives(subject='Thank you', body=order_message, from_email='laksura.com.bd@gmail.com', to=['sohanur.shanto@northsouth.edu'] )
        html_template = get_template('email.html').render()
        html_template = render_to_string('email.html', {'name': o.user, 'order_id': o._id, 'total': o.totalPrice, 'created': o.createdAt})
        email.attach_alternative(html_template, "text/html")
        email.send()

Я получаю эту ошибку

new_conn_created = self.open()

    self.connection = self.connection_class(self.host, self.port, **connection_params)
