Network UPS Tools on Ubuntu VM


HA is running in Vmware Workstation. Due to shortages of Pi’s I have Network UPS Tools setup on a Ubuntu VM. The CyberPower UPS is connected in the Ubuntu VM. The use of VM for NUT is not meant to be a long term solution. I have noticed after 20 or so minutes HA will have difficulty connecting to NUT on a VM. A relative newbie to Linux I am not sure if the service is stopping. From checking within the VM the UPS appears to be connected. In Ubuntu Automatic Suspend is off, but I am noticing after a period of inactivity I have to unlock Ubuntu. Any ideas?
