Conbee II firmware upgrade, zigbee devices offline

I’ve got haos installation on proxmox and using z2m through conbee 2 usb stick.

I’ve decided to update the firmware (from 0x26580700 I think to 0x26780700).
After full restart of the vm, z2m starts and loads all the devices from the files, however non of the devices are seen on the network anymore (last_seen is not updated, none of the commands reach any of the device, none of the device report anything).

I tried enabling paring mode on one of the device and in z2m but nothing changed. I force removed the device and tried adding again - nothing changed. The device hasn’t been added.

z2m logs:

Where should I go from here? That was my first firmware upgrade on conbee dongle and that isn’t the expirence I was expecting… :sweat_smile:

BTW: I’m having no issues running FW 0x26780700 with Z2M.
Hope that helps.

I decided to upgrade the firmware for one specific device as a solution provided on the z2m github. So I wouldn’t really like to come back. Also, the devices are not dropping randomly. It looks like I can’t add any of the devices back again.
