Django can only handle ASGI/HTTP connections, not websocket

Question

Hello I am getting a error.

Before coming here, I tried many different ways and looked at the topics that were opened here before. But whatever I do, it keeps giving me errors.

I tried daphne and uvicorn but the result is the same, it opens in local environment but it does not work on the server and gives this error:

Django can only handle ASGI / HTTP connections, not websocket

My Codes:

Js Code:

<script>

function connectSocket() {
var ws = new WebSocket('ws://' + window.location.host + '/ws/notification/{{request.user.id}}/')

ws.onopen = function(event){
console.log('opened', event);
}

//If there is a long onmessage codes here, I removed the code, no syntax error

ws.onclose = function(e) {
console.error('Chat socket closed unexpectedly; reconnecting');
setTimeout(connectSocket, 1000);
};

ws.onerror = function(event){
console.log('error', event);
}

// window.setInterval(function(){
// loadNotifications();
// }, 1000);
}
connectSocket();
</script>

[CODE]
CHANNEL_LAYERS = {

'BACKEND': 'channels_redis.core.RedisChannelLayer',

},
}



ASGI_APPLICATION = "thesite.routing.application"

asgi

import os
import django
from channels.routing import get_default_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'thesite.settings')

django.setup()

application = get_default_application()

Nginx:

}


location /ws/ {

proxy_pass http://0.0.0.0:9001;

Oh No =( this error is the syntax error

proxy_set_header Connection "upgrade";

Change to :

proxy_set_header Connection “upgrade”;

But now ı give the 404 eror

failed: Error during WebSocket handshake: Unexpected response code: 404

I guess the reason Failure to process ASGI_APPLICATION parameter
