I am running their linux version within proxmox itself (no container/vm). Using this 64 bit installer - https://www.cyberpowersystems.com/p...nel-business/powerpanel-business-4-4-0-linux/ .

The issue is intermittently, the software will stop communicating with the UPS (CP1350PFCLCDa). Software doesn't register a loss of communication event. If I refresh the status page, it will display the same stale data from when it last had communications. Nothing in any logs show loss of communication. When this happens, even disconnecting the cable doesn't register any status changes. Nothing in dmesg either.

Issuing a service ppbed restart corrects it for some interval of time (random). This can be a few hours, a day, 2 days, but is completely random. For now i've set a cron job to restart it every 6 hours, but would like a proper fix. Their customer service suggested going to NUT.

The issue occurs with the ups plugged into both a usb 3 and usb 2 ports. I've also tested usb connectivity on this board by way of external hd with activity every few minutes. No disconnects or other issues.

I'm open to ideas?
