    QUESTION

    Not able to connect to websocket using Nginx and Uvicorn

    Asked 2022-Mar-26 at 10:20

    I built a docker container with Django, Uvicorn, Nginx and Redis, and am using django-channels but when I run this it says it cannot connect to the websocket and this is seen in the browser console:

    WebSocket connection to 'ws://127.0.0.1:8080/ws/notifications/' failed

    It is working fine when I use Django's runserver command for development but when I include Nginx and Uvicorn it breaks.

    Entrypoint.sh:

    gunicorn roomway.asgi:application --forwarded-allow-ips='*' --bind 0.0.0.0:8000 -k uvicorn.workers.UvicornWorker
    

    Nginx config:

    upstream django {
        server app:8000;
    }
    
    map $http_upgrade $connection_upgrade {
        default upgrade;
        '' close;
    }
    
    server {
        listen 8080;
    
        location /static {
            alias /vol/static;
        }
    
        location /ws/ {
            proxy_pass http://0.0.0.0:8000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
        }
    
        location / {
            proxy_pass http://django;
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
            proxy_redirect off;
            proxy_buffering off;
        }
    }
    

    settings.py:

    CHANNEL_LAYERS={
        'default': {
            'BACKEND': 'channels_redis.core.RedisChannelLayer',
            'CONFIG': {
                'hosts': [('redis', 6379)],  #Redis port
            }
        }
    }
    

    The JS file which handles the socket:

    var wsStart = "ws://"    
    var webSocketEndpoint =  wsStart + window.location.host + '/ws/notifications/'
    const notificationSocket = new WebSocket(webSocketEndpoint)
    

    asgi.py:

    application = ProtocolTypeRouter({
        "http": django_asgi_app,
        "websocket": AuthMiddlewareStack(
            URLRouter([
                url(r'^ws/notifications/', NotificationConsumer.as_asgi()),
                path("ws/<str:room_name>/", ChatConsumer.as_asgi())            
            ])
        )
    })
    

    Nginx throws this error with the above code:

    [error] 23#23: *4 connect() failed (111: Connection refused) while connecting to upstream, server: , request: "GET /ws/notifications/ HTTP/1.1", upstream: "http://0.0.0.0:8000/ws/notifications/", host: "127.0.0.1:8080"
    

    When I change the proxy_pass to http://django instead of 0.0.0.0, Nginx does not throw that error anymore but I get the same error on the console. Also this time Django throws these warnings:

    [WARNING] Unsupported upgrade request.       
    [WARNING] No supported WebSocket library detected. Please use 'pip install uvicorn[standard]', or install 'websockets' or 'wsproto' manually.
    

    ANSWER

    Answered 2022-Mar-26 at 10:20

    As noted in a comment by Iain Shelvington, it seems like websockets are not included in the base install of uvicorn

    pip uninstall uvicorn
    pip install 'uvicorn[standard]'
