I am trying to use daphne in django project to handle the websocket connections. I have installed daphne and it seems to be running. However, I am unable to send any websocket connection request. This is my daphne.service file:
[Unit]
Description=WebSocket Daphne Service
After=network.target
[Service]
Type=simple
User=root
WorkingDirectory=/home/django/AysleServer/src
ExecStart=/home/django/AysleServer/MyEnv/bin/python /home/django/AysleServer/MyEnv/bin/daphne -e ssl:8001:privateKey=/etc/letsencrypt/live/djangoadmin.aysle.tech/privk>
Restart=on-failure
[Install]
WantedBy=multi-user.target
On checking the logs of Daphne it shows this:
Started WebSocket Daphne Service.
Starting server at ssl:8001:privateKey=/etc/letsencrypt/live/djangoadmin.aysle.tech/privk...>
HTTP/2 support not enabled (install the http2 and tls Twisted extras)
Configuring endpoint ssl:8001:privateKey=/etc/letsencrypt/live/djangoadmin.aysle.tech/pri...>
Listening on TCP address 0.0.0.0:8001
I thought that http2 and tls were causing the issue so tried to install them in my virtual environment using the command:
pip install -U 'Twisted[tls,http2]'
But they were already present as shown below:
Requirement already satisfied: Twisted[http2,tls] in /usr/lib/python3/dist-packages (18.9.0)
Requirement already satisfied: idna!=2.3,>=0.6 in /usr/lib/python3/dist-packages (from Twisted[http2,tls]) (2.8)

I am using Gunicorn to handle http requests and it works as expected. This is my asgi.py file
import os
import django
from channels.routing import get_default_application
from decouple import config
os.environ.setdefault("DJANGO_SETTINGS_MODULE", f'{config("PROJECT_NAME")}.settings')
django.setup()
application = get_default_application()
and this is my routing.py file:
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.security.websocket import AllowedHostsOriginValidator
from django.urls import path
from wsocket.consumers import *
ws_patterns = [
path('ws/order/', OrderConsumer.as_asgi()),
]
application = ProtocolTypeRouter({
'websocket' : AllowedHostsOriginValidator(
AuthMiddlewareStack(
URLRouter(ws_patterns)
)
)
})
I tried sending the websocket request the following ways:
wss://djangoadmin.aysle.tech:8001/ws/order/
wss://djangoadmin.aysle.tech/ws/order/
But am not able to connect. Please assist me where am I going wrong. Thanks for your time in advance.
