This alway works for me. ( got the solution from a friend)

cd /home/pi/domoticz/plugins/Domoticz-Zigbee/
sudo git stash
sudo git pull --recurse-submodules
sudo pip3 install -r requirements.txt --upgrade --break-system-packages
sudo git submodule update --init --recursive
sudo chmod +x plugin.py ...

Have the same problem

Resolved bij setting domoticz port in https

And set dashticz conf-file also to https

Is it also possible to add the municipality DFM to garbage?
