Server Version#: 1.14.1.5490
Plex Media Server was working fine, but I needed to upgrade storage so moved my media on a new hard drive. Upon doing so, Plex would only find the old copied media and not newly added media.
Tried resetting Plex Media Server (Clearing data and Cache) & Factory resetting the Nvidia shield.
And now it wont find any media at all. It attempts to scan, then comes back with no files found 
Media is located on WD NAS. Confirmed mounted and can be accessed / Folders setup via the Plex.tv
