How to encrypt connection with Django server in react.js ?

Example for a simple gunicorn-one-liner-start:

gunicorn YOURappNAME.wsgi:application --certfile=server.crt --keyfile=server.key --bind YOURip:YOURport --workers 3 --threads 4 --log-file - --access-logfile - --error-logfile - --worker-tmp-dir /dev/shm --log-level info -e PYTHONUNBUFFERED=TRUE --access-logformat '%(h)s %({X-Forwarded-For}i)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(f)s" "%(a)s"'

I use this in a container startscript
