Nginx websocket 代理 Node.js

Question

我正在尝试使用 Node.js 使用 npm package phoenix-channels读取凤凰频道。 Phoenix 通道在 websocket 之上多路复用。 我在我的凤凰网络服务器前使用了 NGINX 代理，所以对于 NGINX，它只是一个 websocket。

凤凰频道工作正常，转到 web 页面，如您所见（您将在web 页面中看到数据）。

它也可以从我的内部网络上的 nodejs 正常工作：

test_chan.js（带有明确的 IP 和端口）：

const { Socket } = require('phoenix-channels')

let socket = new Socket("https://192.168.1.113:4445/socket")

socket.connect()

// Now that you are connected, you can join channels with a topic:
let channel = socket.channel("room:lobby", {})

channel.on("new_msg", payload => {
  console.log(`${payload.body}`);
});

channel.join()
  .receive("ok", resp => { console.log("Joined successfully", resp) })
  .receive("error", resp => { console.log("Unable to join", resp) })

但是，如果我用域名替换明确的 IP:PORT 地址，并从外部运行它，它就不起作用（这里与上面脚本的唯一区别是 URL）：

test_chan.js（通过域名，通过我的 NGINX 代理）：

const { Socket } = require('phoenix-channels')

let socket = new Socket("https://suprabonds.com/socket")

socket.connect()

// Now that you are connected, you can join channels with a topic:
let channel = socket.channel("room:lobby", {})

channel.on("new_msg", payload => {
  console.log(`${payload.body}`);
});

channel.join()
  .receive("ok", resp => { console.log("Joined successfully", resp) })
  .receive("error", resp => { console.log("Unable to join", resp) })

所以 suprabonds.com websockets 通过代理在浏览器中工作正常，但不能作为 nodejs 脚本工作。

这是我的超债券的 nginx conf。com：

启用站点的相关服务器部分：

server {
    server_name suprabonds.com www.suprabonds.com;
    
    location / {
        proxy_pass  http://localhost:4445;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/suprabonds.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/suprabonds.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


}

关于我做错了什么的任何想法？

firefox 工作正常。 其他（其中包含 301 178）来自非工作 Node.js 脚本（即使用域名的脚本）。 同一位置的 error.log 文件为空。
请注意，我也在使用noip动态 dns。

如果您将 URL 更改为：

let socket = new Socket("wss://suprabonds.com/socket/websocket?token=undefined")

或者

let socket = new Socket("wss://suprabonds.com/socket/websocket?vsn=1.0.0")

它将连接
