deploying on glitch and connecting from node

[scenaristeur]

user agent could be "WebSocket Client" instead of "firefox"

this adds the ability to connect from nodejs client adding a User-Agent header

That is probably a firewall or proxy issue on your side.

WebSockets don't support headers (in the browser), so I don't want to add this feature, as it would be nodejs specific.

If you still want this feature, you could try adding a wrapper around WebSocketPolyfill:

new WebSocketPolyfillPolyfill extends ws.WebSocket {
  constructor(...args) {
    super(...args, { header: '...' })
  }
}
