如何在Nginx服务器中配置Daphne通道

Question

我有一个 Django 应用程序，可以同时处理 http 和 websocket 请求。该应用程序在本地正常运行。我已在 Nginx 服务器中配置了 Gunicorn 和 Daphne 服务，但即使未发出请求，Daphne 服务也会在启动后几秒钟内自动停止。结果，未建立 websocket 连接。几个月来我就面临这个错误，并尝试了各种可用的解决方案，但没有任何效果。

/etc/nginx/sites-available/myapp

upstream websocket{
     server 0.0.0.0:8001;
}

server {
    listen 80;
    server_name mydomain.com;

    location = /favicon.png {
        access_log off;
        log_not_found off;
    }

    location /static/ {
        root /home/ubuntu/projects/my_app;
    }

    # WSGI
    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }

    # ASGI
    location /ws/ {
        proxy_pass http://websocket;

        proxy_http_version 1.1;
        proxy_set_header Origin "ws://mydomain.com:8001";
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Host $server_name;
    }
}

路由.py

from django.urls import re_path
from . import consumers
websocket_urlpatterns = [
    re_path(r"ws/video/start/$", consumers.VideoStartConsumer.as_asgi()),
]

我正在尝试配置 Daphne 通道来处理 websocket 请求，但 Daphne 服务在启动后几秒钟内自动停止。
