Lost connection to all Zigbee devices after Update

Hallo to all.
First of all i have allready learnd a lot with the configuration of my Home assistent but im still noob in terms of Programming and configuration. So thank you for your easy to understand feedback:-)

I run home Assistant on a Virtual Machine on my Synology 918. i Had some troble to set up the conbee 2 stick but i get everything working after some try and error.

After the last update i made i lost connection to all my Zigbee devices.
they show still !

but they are all not available

All the devices ( about 20) are installed around the house.

? do i have to reconnect all deviced individual or is ther a solution to reconnect the devices ?
Thanks guys for your help and time
