Hi,

I got really frustrated from the fact that the latest software on my Homey Pro (first version) often has bad connections with the new app. But now for some reason I can also not update my app anymore because the command line version is not working:

```auto
homey app run
× Error: websocket error
    at Transport.onError (C:\Users\info\AppData\Roaming\npm\node_modules\homey\node_modules\engine.io-client\lib\transport.js:68:13)
    at ws.onerror (C:\Users\info\AppData\Roaming\npm\node_modules\homey\node_modules\engine.io-client\lib\transports\websocket.js:163:10)
    at WebSocket.onError (C:\Users\info\AppData\Roaming\npm\node_modules\homey\node_modules\engine.io-client\node_modules\ws\lib\event-target.js:140:16)

    at HTTPParser.parserOnHeadersComplete (node:_http_common:119:17)
    at Socket.socketOnData (node:_http_client:535:22)

```

Ping to device goes okay. Also DNS test works fine. Removed everything and reinstalled the CLI.

```auto
npm install --global --no-optional homey

```

same result.
