All Files disappering on SMB External Storage

Running Version 9.1.1.3

I have an Ubuntu VM running on Hyper-V on Windows 10 Pro using an SMB share for a folder named "Client Files"

The files just disappeared this morning.

Looked at the share on Windows and everything was there as it should be.

I had a green dot on the external storage admin area for all the SMB shares.

Rebooted the OC VM. - not fixed.

I went into Windows to the folder and created a new folder named "test" - now the files are there again.

What could be going on?
