Don't know if any extra info is needed on this, but I encountered this issue and discovered during traces that the folder queried on the SMB server is actually 2x the subfolder specified in the config.

E.g., if I configure server 1.2.3.4, share MyShare$, subfolder: Projects/Subproject,
I see queries happening for folder: "Projects\Subproject\Projects\Subproject"

Without more details I can't say for certain, but this may have been addressed by #43349 (which was released in 28.0.3 a few weeks after your report).
