seems like I have a problem with the persistent volumes of these dockers.
When using the script I wondered why the IP does not change and weird things happen.
But after trying to change \jitsi\jitsi-meet-cfg\web\config.js from meet.jitsi I recognized, that each time a docker is restarted or even only stopped and started again via portainer, the config files are rewritten.
That's not normal behaviour, is it? 😅
