Node Red lost contact with Home Assistant after upgrade to 0.104.3

Please help! I upgraded from 0.104.2 to 0.104.3. Nothing else is done.
Now Node Red (hassio add-on) is unable to execute call service. The node red log is full of “Call-service API error.”
I have tried restarting everything, and reboot, and uninstall/reinstall node red. Nothing helps.
I also have the same problem with zigbee/deCONZ. Node red is unable to connect to it. I have changed the port to 40850.
What can I do?

Uninstalling/reinstalling most of my addons, and a few restarts/reboots, and it looks okay. A bit frightening, I think. Next time I upgrade, I’ll make a complete backup first.
But for now, I’m very happy with 0.104.3!
