Windows 10 sleeps fine from menu, won't sleep from timeout

I have a power meter on a Windows 10 box. If I sleep from the menu, it drops down to about 3 watts. If I wait for a timeout (set at two minutes) it blanks the screen but keeps using the same amount of power.

I've noticed that browser tabs with videos or ads, even if paused will block sleep. But closing those is not enough, there's something about the network:

C:Windowssystem32>powercfg -requests
DISPLAY:    None.

SYSTEM:    [DRIVER] FileSystemsrvnet
An active remote client has recently sent requests to this machine.

AWAYMODE:    None.

EXECUTION:    None.

PERFBOOST:    None.

This is a newly installed machine with a major brand motherboard. No specific file sharing is in use, there are no other windows machines on the local network. How can I get this machine to automatically sleep based on the timer? Which "remote client" might the problem be?

I have read the old thread https://social.technet.microsoft.com/Forums/windows/en-US/784f203d-0103-4272-8884-e4d4834b11db/sleep-blocked-by-active-remote-client?forum=w7itprogeneral See similar questions each with less detail: Windows 10 won't sleep, even after overriding drivers and Windows 10 PCs not sleeping after automatic wake (sometimes) and Windows 10 doesn't sleep
