Nginx websocket 代理 Node.js

Question

我正在嘗試使用 Node.js 使用 npm package phoenix-channels讀取鳳凰頻道。 Phoenix 通道在 websocket 之上多路復用。 我在我的鳳凰網絡服務器前使用了 NGINX 代理，所以對於 NGINX，它只是一個 websocket。

鳳凰頻道工作正常，轉到 web 頁面，如您所見（您將在web 頁面中看到數據）。

它也可以從我的內部網絡上的 nodejs 正常工作：

test_chan.js（帶有明確的 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，如果我用域名替換明確的 IP:PORT 地址，並從外部運行它，它就不起作用（這里與上面腳本的唯一區別是 URL）：

test_chan.js（通過域名，通過我的 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 通過代理在瀏覽器中工作正常，但不能作為 nodejs 腳本工作。

這是我的超債券的 nginx conf。com：

啟用站點的相關服務器部分：

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


}

關於我做錯了什么的任何想法？

firefox 工作正常。 其他（其中包含 301 178）來自非工作 Node.js 腳本（即使用域名的腳本）。 同一位置的 error.log 文件為空。
請注意，我也在使用noip動態 dns。

如果您將 URL 更改為：

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")

它將連接
