You can thank Apple for that because for mostly financial reasons, macOS has a non-standard implementation of SMB than anybody else, it is frequently incompatible with Linux, BSD and Windows.

You can go ask Apple support long enough, and they will tell you they don’t support third party network storage and users should use Apple cloud storage.
This is one way Apple has managed to improve their operating margin over the last 15 years by preventing competition in their business.
Obviously ‘Clear Device Setting’ helped, just as long as macOS doesn’t write to the MCH.
You can see an example of the macOS permission errors plain as day here :
