带Laravel-echo-server的WebSocket：502错误的网关

我找不到一个多星期的解决方案。一切在开发服务器上都可以正常运行，但在生产环境上却无法正常运行。我没有力量，我向你呼吁，同事们：）

我正在使用CloudFlare在Socket.io上使用Laravel-echo-server。尝试连接时，出现错误：WebSocketError：收到意外状态代码（502错误网关）

Ubuntu 16.04.7 LTS，Laravel Echo Server：1.6.1，NodeJs：v12.19.0

laravel-echo-server.json：

    {
    "authHost": "http://localhost",
    "authEndpoint": "/broadcasting/auth",
    "clients": [
        {
            "appId": "...",
            "key": "..."
        }
    ],
    "database": "redis",
    "databaseConfig": {
        "redis": {
            "password": "...",
            "port": "...",
            "db": 0
        },
        "sqlite": {}
    },
    "devMode": true,
    "host": "",
    "port": "6001",
    "protocol": "http",
    "socketio": {
        "transports": ["websocket", "polling"]
    },
    "secureOptions": 67108864,
    "sslCertPath": "",
    "sslKeyPath": "",
    "sslCertChainPath": "",
    "sslPassphrase": "",
    "subscribers": {
        "http": true,
        "redis": true
    },
    "apiOriginAllow": {
        "allowCors": true,
        "allowOrigin": "*",
        "allowMethods": "GET, POST",
        "allowHeaders": "Origin, Content-Type, X-Auth-Token, X-Requested-With, Accept, Authorization, X-CSRF-TOKEN, X-Socket-Id"
    }
}

Nginx主机：

    server {
        listen 8443 ssl;
        server_name domain.tld;       
        ssl_certificate /etc/nginx/ssl/my.crt;
        ssl_certificate_key  /etc/nginx/ssl/my.key;
        error_log /var/log/nginx/domain.tld/ws.log info;

        location /ws {
                proxy_pass http://127.0.0.1:6001;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "Upgrade";
        }
}

启动EchoServer之后，我看到：

L A R A V E L  E C H O  S E R V E R

version 1.6.1

⚠ Starting server in DEV mode...

✔  Running at localhost on port 6001
✔  Channels are ready.
✔  Listening for http events...
✔  Listening for redis events...

Server ready!

好，接下来：

$ curl 127.0.0.1:6001
> OK

下一个：

websocat wss://domain.tld:8443/ws

我得到了错误：

websocat: WebSocketError: Received unexpected status code (502 Bad Gateway)

Laravel回显服务器正在运行，我可以看到其事件。尝试将nginx代理中的laravel-echo-server.json（127.0.0.1，localhost，null，0.0.0.0）中的主机更改为localhost，127.0.0.1-没有任何帮助。我试图在nginx主机中添加上游，这没有帮助。该信息也没有帮助：https : //github.com/tlaverdure/laravel-echo-server/issues/273
