ZWAVE JS Inovelli device not connecting

I am running Home Assistant (21.6.6) on a Raspberry Pi.
I installed ZWAVE JS in SUPERVISOR.
I installed ZWAVE JS in CONFIGURATION.
Yesterday, I was able to add a node (3) a Inovelli LZW31-SN Red-Series Dimmer.

For some reasons, it stop responding this morning. I tried to add the node again, without success. I even factory reset the unit (holding the config button for 20 seconds). I cannot add the node. ZWAVE JS (config) indicate that I have 2 devices my Z-Stick Gen5 (node status : Alive; node ready; YES) and Node 3 (node status : DEAD and node ready : NO.

Any suggestion how to remove this node and reinstalled my switch
Other question: how do I subscribe to ZWAVE JS log message. My configuration ZWAVE log does not show anything.
