Zigbee2MQTT is not working correctly any more

Zigbee2MQTT doesn’t allow new devices to be added to the network anymore. I don’t know since when.

Also the Map is weird, far fewer connections showing up than I once had on there and many devices without connection are working fine.

I noticed after I decided to repair a smart bulb which was taking up to two seconds to respond to a change. I was able to repair but the interview did not finish. Its an IKEA LED1924G9.

Pairing new devices either failed with an unknown device or no device at all. The IKEA LED2109G6 I tried is compatible for sure.

Does anyone have any suggestions that do not risk loosing the rest of my network?

Hardware:

Pi4

Sonoff Zigbee Dongle P

Try stopping z2m, re-plugging the adapter and starting z2m again.

I did that. No change.
