Django EmailBackend ConnectionRefusedError from app on PythonAnywhere

My password reset feature was working fine in development, sending a password reset email, but now that I have deployed to PythonAnywhere, I am getting a ConnectionRefusedError, specifically:

ConnectionRefusedError at /reset_password [Errno 111] Connection refused Request Method: POST Django Version: 4.1 Exception Type: ConnectionRefusedError Exception Value:
[Errno 111] Connection refused Exception Location: /usr/local/lib/python3.10/socket.py, line 833, in create_connection Raised during: django.contrib.auth.views.PasswordResetView Python Executable: /usr/local/bin/uwsgi Python Version: 3.10.5 Python Path:
['/var/www', '.', '', '/var/www', '/usr/local/lib/python310.zip', '/usr/local/lib/python3.10', '/usr/local/lib/python3.10/lib-dynload', '/home/gridsquid/.virtualenvs/myvirtualenv/lib/python3.10/site-packages', '/home/gridsquid/gridsquid'] Server time: Sat, 12 Nov 2022 16:45:30 +0000

I have verified the user is a valid user with a working email address.

in settings.py:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'apikey' # Name for all the SenGrid accounts
EMAIL_HOST_PASSWORD = os.getenv('SENDGRID_API_KEY')

in urls.py

path("reset_password",
    auth_views.PasswordResetView.as_view(template_name="gridsquid/reset-password.html"),
    name="password_reset"),
path("reset_password_sent",
    auth_views.PasswordResetDoneView.as_view(template_name="gridsquid/reset-password-sent.html"),
    name="password_reset_done"),
path("reset/<uidb64>/<token>",
    auth_views.PasswordResetConfirmView.as_view(template_name="gridsquid/reset.html"),
    name="password_reset_confirm"),
path("reset_password_complete",
    auth_views.PasswordResetCompleteView.as_view(template_name="gridsquid/reset-password-complete.html"),
    name="password_reset_complete"),

Again, everything is working in my development environment. What could be wrong here?
