module 'lib' has no attribute 'OpenSSL_add_all_algorithms'

[s-kvng]

Any time I run this command "python manage.py runserver_plus --cert-file cert.crt"... I get an error. Already downloaded the packages, but still doesnt work. This is from chapter 5

I ran into the same issue and fixed it by adding cryptography==38.0.4 line to requirements.txt and then running pip install -r requirements.txt.
