Well actually that's it, the only other changes I had to do was adding websocket support to nginx config, install uvicorn and use its worker class from systemd and then update asgi.py

This could serve as example production deployment docs:

Nginx websocket support to add to server config (with certbot enabled)

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

Install uvicorn

sudo apt get install uvicorn[standard]

Run uvicorn like so from systemd service file via ExecStart=

gunicorn asgi:application -k uvicorn.workers.UvicornWorker ...

asgi.py

import os
import django
from channels.routing import get_default_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'gama.settings')
django.setup()
application = get_default_application()

Not sure what's wrong with tests, could you help me with that?
