Can't pair a Hue dimmer in zigbee2mqtt

I have a KVM based Hassio with host shared Deconz Conbee II USB.
I installed Zigbee2MQTT and based on these logs it connects properly to /dev/ttyACM0
See the logs:

Zigbee2MQTT:info  2022-06-17 20:43:50: Connected to MQTT server

The problem is that when I permit to join other devices, also following the device dedicated pairing instructions, nothing happens:


No sign of life in the logs neither.

Any clue what how to troubleshoot or perhaps you’ve seen this before?
