Not Reconnect after RSTP restarted or new websocket conection

[rifalgrp]

So i have express server running on ubuntu with pm2, i have follow sample usage with many cameras, let say i have 3 camera than i start server with pm2 start express.js, everythings work perfectly, but let say if one or two camera is shutdown and power on again i cant see stream that one or two camera until pm2 restart express. its also happen if i add 4th camera dynamically just change ws parameter right? but i still need to pm2 restart express for it works.

express code

const express = require('express');
const app = express();
const { proxy, scriptUrl } = require('rtsp-relay')(app);
process.setMaxListeners(0);
app.ws('/api/stream/:cameraIP', (ws, req) =>
    proxy({
        url: `rtsp://user:pass@${req.params.cameraIP}/Streaming/channels/102`,
        additionalFlags: ['-q', '1'],
        transport: 'tcp',
    })(ws),);
app.listen(2000);

then my frontend vue js

loadPlayer({
   url: domain + ipCam,
   canvas: document.getElementById("video-canvasX" + this.canv),
});

How i can handle this problem without pm2 restart express when :

• camera off and on again
• add new camera
  this dynamic websocket /api/stream/:cameraIP not working before pm2 restart

thanks
