Hi 
I have HA 2022.12.8 (via Docker) and a Texas Instruments Z-Stack ZNP protocol: CC253x, CC26x2, CC13x2 coordinator with FW 20220219.
I set ZHA up with all my lights and sensors which worked well! I had to do some things and switched the whole system off a few days. Im done (some rebuilt, nothing on the HW/SW side) and started everything back on - since then, NO single ZigBee device is connecting anymore.
The nearest sensor is 50cm away from the coordinator, the next one switch some meters. But even the other sensors anywhere in the house (which were connecting before) are “lost”.
Switched on debug:

2023-01-02 12:07:14.908 INFO (MainThread) [zigpy_znp.zigbee.application] Permitting joins for 0 seconds
The only notice I wonder about was: 2023-01-02 12:07:14.908 INFO (MainThread) [zigpy_znp.zigbee.application] Permitting joins for 0 seconds - is that right?
What can I test now? Or is there some ZigBee protocol rule which prevents too many connects from an enddevice in case of failure? Do I have to wait a few hours and all will be back?
I dont see any debug packets recieves when I press my Lumi switch direct near the coordinator - should I?
Thanks in advance!
