Zigbee2Mqtt: Devices are nit available

Hi,

scince some weeks I have got the problem that my HA isn’t able to connect to most of my Zigbee devices.

I haven’t any notable changes.

I am using a Conbee II stick.

And the strange thing is that only the Aqara devices are connected.

Have you got any idea how to debug this?

Greetings
Andre
