Problem with adding node to Ha


I have a weird problem. I have HA on docker on Pi3. My zwave controller is Aeon labs z-stick Gen5. Everything was fine till yesterday. I added one more wall switch to my network (have few already from the same vendor), it was OK for some time but then it went dead. Tried everything to put it back alive, heal, test, restarting HA etc. Finally decided to remove it from the network. After reboot it disappeared but now i cant add it again. When i start “add node” service and put the switch into inclusion, nothing happens. Can anyone help ?
