All of my shared users are getting a "There was a problem playing this item" error message when trying to play videos with the webapps (Chrome, Firefox, IE). Vizio TV app (Opera based) also doesn't work. Using a Fire TV works fine.
In the log files I am seeing the following message:
ERROR - TranscodeUniversalRequest: Client attempted to request remote content without permission: 'http://127.0.0.1:32400/library/metadata/26177'
Full log file has been attached.
