gaierror when trying to send email with Django using Google App Engine

[James Brace via StackOverflow]

I have deployed a Django project on Google App Engine and have set up django-password-reset in order for users to be able to reset their password through email verification.

However, when I try to submit the recovery request I get this error:

I am new to working with sockets and Google App Engine and was wondering if anyone could help me decipher this error message. Thanks

    EMAIL_HOST_USER = 'Your...@gmail.com'
    EMAIL_HOST_PASSWORD = 'password'
    EMAIL_PORT = 587
