but a text search (Google) isn’t finding anything like that. Somewhat similar ends were in 2018 and 2017.
What are operating system (and if not Windows, mono --version), Duplicati version, and storage type?
The other slightly similar issues were on S3, so if that’s the case, then what compatible destination is it?

Is this a new setup or did an old one die? Test new one with Duplicati.CommandLine.BackendTester.exe, giving it an empty folder and a target URL similar to what your job Export As Command-line will give you.

Solved, by mistake, I add network drive to backup.
