(HELP!) My XBox one with Plex sound pauses halfway, then video stops and is fine if I skip ahead

Plex Players Gaming Consoles
1

Details:
Xbox One, connected via Ethernet (Under DMZ and assigned Static IP within router)
Router: Asus AC-3100
Computer Asus Laptop: X555QA (Using 5G Wi-Fi) signal to AC-3100
Media type: X264 MP4
My movies are aldreay MP4 and previously used via Itunes and Apple TV. So transcoding is not needed.

Any fairly large movie, I would say, 8 GB or higher in size, causes what I described in the title

I have attached the log files.

Please help.

Thank you.

Please note:
The last movie that caused this issue was the Guardians of the Galaxy movie I just streamed. ( about 30 mins ago)

Update: Still going bad, currently streaming John Wick 2, no transcoding…
