MinimServer is preventing my Synology NAS from hibernating

[Vladino]

Hello @all!
I'm a new user of MinimServer and I have been testing this software for the past 2 month. It's everything that I have ever wanted, it fits all my needs but I have a problem with hibernation.
I run MinimServer from a dedicated Lenovo ThinkStation P330 Tiny (i7 8700, 32 GB RAM, 2 TB Samsung 990 Pro SSD, Windows 10 Pro). When running MinimServer my PC won't hibernate. It runs ONLY MinimServer, no other server or software. If I close MinimServer the PC hibernates. I've checked the log level as sugested and I'm on default configuration so loglevel is set to "info". Also I've checked when running MinimServer in comand prompt with "powercfg /requests" command and I can't see any process that is preventing my PC from going to sleep .
Any help would be much appreciated. Beside this issue all is excellent related to this software. This is the only problem I'm faceing.

Kind regards,
