Folder is not available or deleted after reset

Hello.
I have roon running on my Mac OS X 10.11.
I’ve added Watched Folder from my disk station and everything works fine. But whenever I restart my Mac there’s an error that is folder is not available or it is deleted. Then I need to remove it from my watched folders and add it once again.
What can possibly cause it and how can I fix it?
