Plexmediaserver trouble after SD card replacement

Looking for some help. After several re-installs and a lot of searching i cannot figure this out. I recently had an SD card failure and replaced the damaged card. Previous installation on the old card worked great. Plex installs fine using dietpi-software. Able to connect to :32400 but cannot add my media libraries. Clicking “Your Media” prompts me to download plex server. Dietpi-services shows plexmediaserver is running.

I guess the web frontend runs but the server backend not. Please check the service status and logs:

systemctl status plexmediaserver
journalctl -u plexmediaserver

That’s what i thought too. Your suggestion gave me some clues and I have it resolved. Service was disabled and we have enabled it now. also not sure if it was related but ran

sudo locale-gen

to fix locale issue.
