My zigbee network is down

[cuongdm75]

I'm using raspbee II in Pi 4B, it was run for over 2 years with only some minor issues. Last week my zigbee network was down, I tried to reload zha, reboot the system and it could work for sometimes. At the last I tried to reinstall fresh system and added all my devices again. It work for 2 days until today, it is down again.

Here is the log in my home assistant:
