All zigbee2mqtt devices became unavailable

Installation
1

Hello,
I’ve installed Home Assistant and added a few dozens of devices using zigbee2mqtt and the SMLight slzb-06m That worked well for several weeks.
This morning, none of the devices were working anymore, they all appeared “unavailable” as if they were all disconnected 7 hours ago.
I then restarted HA (upgrade it to the latest version at the same time), the mosquitto server, the zigbee2mqtt integration, the slab-06m, but it was pretty much the same things (only Matter devices seemed to be ok in the UI).
Then, everything started to work again after a few tens of minutes.
TBH, I don’t what I’ve done that fixed the problem.
Have you already encountered this kind of issue ?
Thanks for your help.

Did you check the Zigbee2MQTT logs ?

I did not check when I add the issue and then I upgrade HA and restarted Zigbee2mqtt. So now it’s too late :cry:
Next time, I’ll check the logs right away :wink:
