Django WSGI and ASGI

How can I run the ASGI and WSGI protocols separately in my Django project?

This is my project structure.

setting.py file

ALLOWED_HOSTS = ["*"]
INSTALLED_APPS = [
    "daphne",
    ...,
    ...,
    "chat",
]

# for HTTP protocal
WSGI_APPLICATION = "config.wsgi.application"

# for Websocket protocal
ASGI_APPLICATION = "config.asgi.application"

chat/urls.py file

from django.urls import path
from . import views

urlpatterns = [
    path("", views.index, name="index"),
]

wsgi.py file

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings")

application = get_wsgi_application()

chat/routing.py file

from django.urls import re_path
from . import consumers

websocket_urlpatterns = [
    re_path(r"ws/chat/(?P<room_name>\w+)/$", consumers.ChatConsumer.as_asgi()),
]

asgi.py file

from chat.routing import websocket_urlpatterns

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings")

application = ProtocolTypeRouter(
    {
        "websocket": AllowedHostsOriginValidator(
            AuthMiddlewareStack(URLRouter(websocket_urlpatterns)),
        ),
    }
)

After setting up all the configurations, I ran the HTTP and WebSocket servers on separate ports:

  1. Run the HTTP server (with Gunicorn): 
     gunicorn config.wsgi:application --bind 0.0.0.0:8000
  2. Run the WebSocket server (with Daphne): 
     daphne config.asgi:application --bind 0.0.0.0 --port 8001```

After running these servers, when I visit http://0.0.0.0:8000 in the browser, it works correctly. However, when I try to connect to the WebSocket using ws://0.0.0.0:8001/ws/chat/private-room/, it fails to connect. Can someone explain why it fails to connect? In the asgi.py file, I do not want to use "http": get_asgi_application() in the ProtocolTypeRouter mapping like:

from django.core.asgi import get_asgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings")

application = ProtocolTypeRouter(
    {
        "http": get_asgi_application(),  #  i do not want to use this.
        "websocket": AllowedHostsOriginValidator(
            AuthMiddlewareStack(URLRouter(websocket_urlpatterns)),
        ),
    }
)
