Time Machine fails in Power Nap

2020 13" Pro M1 connected to QNAP NAS. If I manually run Time Machine it works just fine. However, it doesn't work in Power Nap. I used TimeMachineEditor to schedule a backup at 2am but it never works. Question: I can't find any logs of it failing at 2am. How can I force backupd to log why it isn't working? How do I know it even woke up and tried at 2am? Edit: Mac is plugged in, NAS is always on, network is fine.
