I am trying to connect django channel 3 but it is connection rejected

Using Django Async/Channels
1

ASGI

import os
from .consumer import MyConsumer
from django.urls import path
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.security.websocket import AllowedHostsOriginValidator
from django.core.asgi import get_asgi_application

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

django_asgi_app = get_asgi_application()



application = ProtocolTypeRouter(
    {
        "http": django_asgi_app,
        "websocket": AllowedHostsOriginValidator(
            AuthMiddlewareStack(URLRouter([path('ws/chat/',MyConsumer.as_asgi())]))
        ),
    }
)

*Consumer

from channels.generic.websocket import WebsocketConsumer

class MyConsumer(WebsocketConsumer):
    groups = ["broadcast"]

    def connect(self):
     
        self.accept()
     
        self.accept("subprotocol")
      
        self.close()

    def receive(self, text_data=None, bytes_data=None):
        self.send(text_data="Hello world!")
        self.send(bytes_data="Hello world!")   
        self.close()
        self.close(code=4123)

    def disconnect(self, close_code):
                pass

Redis also tried inmemory

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("127.0.0.1", 6379)],
        },
    },
}

console output

WebSocket HANDSHAKING /ws/chat/ [127.0.0.1:49645]
WebSocket REJECT /ws/chat/ [127.0.0.1:49645]
WebSocket DISCONNECT /ws/chat/ [127.0.0.1:49645]

Well, there’s a lot that can be the root cause of your issue.

Since you have:

  • AllowedHostsOriginValidator activated, what are your ALLOWED_HOSTS setting?
  • AuthMiddlewareStack activated, are you logged in?
