Some Clients Won't Play Media - PMS - MacOS

Server Version#: 1.20.3.3421-54b6523bd
Player Version#: 1.20.0.1406-f47a81b7

Recent update to PMS in the last week has caused most clients platforms to fail to play.

- nVidia shields - 1 of 2 failed, responded after factory reset on the shield
- Roku - remote user on v6.6.11
- Plex for Mac - fails (“unknown error”)

The attached server log shows both server and client on same ethernet (wired) network.
