Homey app run (command line interface) - websocket error

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:

homey app run
× Error: websocket error

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

npm install --global --no-optional homey

same result.
