Z-wave dead between 4 hours to 2 days after restart

Hello

I am running HA on proxmox.
HA is updated

Zwave stick - aeotec gen 5
around 70 devices.

So to my issue for the last 6 months.

After some times when all works as it should it stops working. (only z-wave, zigbee works great)
often i get away with just do a restart on addon z-wave js ui and then it works, but sometimes i need to do a full power down of the proxmox.

Are there anyone that could help me along the road to fix this. I can provide logs but not sure witch logs to provide.

Thanks
Koml
