I can't get screencast to show up longer?

[fribse]

Not sure what the h… happened here.
My MMM-Screencast doesn’t show up in the Youtube app any longer.

I did a reinstall with

git clone https://github.com/kevinatown/MMM-Screencast.git
cd MMM-Screencast
npm install

Config looks like this

{
      module: "MMM-Screencast",
      position: "bottom_right",
      config: {
        castName: "Spejl",
        position: "bottomCenter",
        height: 600,
        width: 800,
      }
    },

Just to be sure that I had the latest, but nothing shows up.
Is there a special trick for this?

Looking in the logs, I did find something, but I don’t understand the meaning, except that it says it’s already listening?

I looked a bit with
sudo netstat -tulpn | grep LISTEN
And without MagicMirror running it shows

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      490/sshd

with MagicMirror it shows

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      490/sshd

tcp6       0      0 :::22                   :::*                    LISTEN      490/sshd
tcp6       0      0 :::8569                 :::*                    LISTEN      5754/electron.js

So the port 8569, isn’t that screencast? If I uncomment the screencast config, it doesn’t show the port as opened…
So why doesn’t it show up in the app?
