Need help to configurate deCONZ app for Home Assistant and Homey

Robert, hi.
Please help. I was happily running deconz 1.29.2 until it “The app unexpectedly stopped”.
Things that didn’t work:
Restarting app
Rebooting pi
Rebooting Homey

The app’s configuration page fields are all empty so I tried autodiscovering (the pi is on the static address, I input the ip address, port 8081 and websocket port 40850, hit Authenticate app in Phoscon), but it just gives me a timeout error.

The only thing that changed was the installation of the pihole ad blocker/DNS server at the time. Thinking Pihole may have screwed up port access (from this point I had a very vague idea of what I was doing), i installed ufw and explicitly sudo ufw allow 8081 and just in case the 40850 as well, while I was at it.

Tried the discovery/requesting key again - no dice.

I will uninstall pihole tomorrow but maybe there’s something obvious I screwed up so it can be fixed or checked easily.

I sure hope pihole is somehow the culprit and not vengeful Athom disabling the unmaintained app. Today.

Thank you very much!!!
