I have not edited a single file, including anything to do with NUT, on the Synology via ssh.... ever. How is yours configured in the UI? Do you have it set to go into safe mode after a certain number minutes?

Earlier, I was just copying and pasting the contents of some files to Roger but did not change anything.

The slaves shutdown, then eventually the master, but the Synology never powered down and the UPS powered off which cut the power to it while it was still on.  Anyone know what the heck is going on?  I’m feeling a bit cursed, haha.

I wonder this because with a stock Synology UPS configuration as a NUT client to my RaspberryPi NUT server, my Synology does power off properly. I do not know if there is a way to restore the Synology's UPS config files to the default configuration, though that might be a worthwhile endeavor for your NAS.
