Pi-Hole not working after updating to latest Umbrel 0.4.3

A couple of days ago straight after updating Umbrel to the latest version 0.4.3 pi-hole died. I cannot access it via the usual location. It’s not blocking websites. If I point my traffic to it, I cannot access the internet. Seems that it’s really not operating at all. Tried uninstalling it and reinstalling - no luck. How can I trouble-shoot further? many thanks

turns out the pi-hole PI address just changed
