ReadyNas RN214 Plex App Not Initializing

Hi,

I have been happily running Plex Media Server from my ReadyNAS RN214 for a year or so but suddenly the plex server app will not initialise at all. I have reinstalled it a couple of times. Each time i first launch it i get this error (i have tried all the suggestions) :

After the first time i try and launch the app, it turns itself off and then refuses to turn back on again giving the following message:

Any suggestions on how to get Plex Server back up and running would be most appreciated.

I will try and keep the firmware and apps up to date:

ReadyNAS Firmware 6.10.8

Plex v 1.32.0.6918-6f393eda1 - April 6, 2023
