Hi, Thank you for getting back to me so quickly.
I have re-analysed all the problem episodes. I have re-installed plex on my TV and added my TV’s IP to the list of IP addresses and networks that are allowed without auth.
It still doesn’t play these files.
Please see attached, new logs. Plex Media Server Logs_2020-08-31_19-29-55.zip (1.8 MB)
I have attached the XML too.
