iMac 2020 macOS 12,4 : SMB sharing files won't connect when computer is on sleep mode

[SoYoung]

Since I got my new mac a month ago, I noticed that SMB sharing files won't work when the iMac enter sleep mode and will only work when the computer is active. The thing is, I absolutely changed anything from my old 2015 iMac (transferred from a full time machine backup)

On my old mac, SMB worked all the time. Anyone have this problem or have any fix? Thanks!

Have you checked that Power Nap and/or Wake for network access is enabled in the Energy Saver System Preferences?

Yes both are enabled.
