Can't uninstall or re-install Plex - Plex broken

My Cloud OS 5 My Cloud EX
1

Hi folks.
I’ve been using Plex successfully for months on my MyCloud EX2 Ultra, but all of a sudden it stopped working. I tried uninstalling and re-installing, and have even tried installing a new binary manually. Nothing seems to work. I also did a system restore to see if that would help, but no joy…

If I look at the Apps installed now, it shows Plex is installed. If I try to uninstall, and then reboot, it still shows as installed. If I click on Configure, all I get is a ‘Not Found’ message. You can see the problem here…

Any ideas would be very gratefully appreciated.
Many thanks for reading

======================================================

UPDATE -
I’ve managed to fix this by accessing the MyCloud via SSH. I followed instructions found here

Strangely I wasn’t able to remove the ‘plex_conf’ folder, but removing the ‘plexmediaserver’ seems to have done the trick.

===================================================
UPDATE 2
For anyone coming across this issue, I found the answer was to SSH into the MyCloud device, and remove the plex folders manually. THis is the process:
cd /mnt/HD/HD_a2
rm -rf plex_conf
cd Nas_Prog
rm -rf plex_conf
rm -rf plexmediaserver

Hello,
I’m running into something similar I think. I have been running Plex on my PR4100 for several years now. Suddenly, I can’t reach my server via web browser (“this site cannot be reached” error), or any of apps on my phones or Roku. I CAN login to the WD admin page as you have here, and I can also reach the NAS via mapped network drive in Windows Explorer…IOW, the NAS server and my networking seem fine.

Do you think if I SSH into the server and delete the Plex config folders I can get my Plex Server working again? These commands are totally greek to me - Can you confirm that using these commands will have no affect on my DATA (stored media), just the Plex configs?

Thanks!
