Remote (NAS) folders not available - LR toggles the status all the time.

[Slonek]

Hi,

I've encountered strange issue with LR. All my photos are securely stored on NAS drive and in LR I just have smart previews. However, LR started to toggle whole folder tree between available / unavailable states so that I can't work on photos comfortably anymore.

Just to exclude some obvious answers:

1. I haven't observed any issues with NAS drive (like access issues etc.) - I am using it for other purposes as well (streaming video and music) - everything works perfectly
2. Local system - Win10 with all latest updates, administrator account
3. Wired connection (TP, hub)
4. NAS folder with photos is shared under account that has all rights to files (r/w)
5. From my system I can access NAS shared folder freely and create, remove files etc. - even when LR reports missing folders
6. THE ONLY other thing I've observed that might be connected to the issue is that I can't create folder within folder through LR (error message that folder can't be created) - still, LR is able to write and delete files from NAS folder freely ( e.g. during export or when removing source photos)

This issue was annoying, now looks like show stopper as it happens all the time...

Any guesses? What should I check first?
