Zigbee2mqtt lost connections how to recover

Sometime last night I lost all my Zigbee connections (devices, routers and coordinator).
I was able to get back my devices by rebooting all 30 of them. Also got the coordinator working.
But I still can’t get back any of the Sonoff Zigbee Plus dongels I have in the house.
I unplugged them, waited and replugged back in but still no connection.

What step am I missing to ge them going.
Any help appreciated.
Thank you.
