PlexMediaServer on Linux not listening on 32400

Plex has been working great for years.
I added a new router and couldn’t get the port forward rules to forward thru the bridge.
Long story short reboots and a yum update, now Plex doesn’t work.

Of course I can ping it by the IP, but can’t open the IP:32400/web that has always worked.
Firewall not running:
service firewalld stop

Plex process not listening on 32400
netstat -nlp

service status plexmediaserver

Shows running but:
Failed to load preferences at /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Preference

Package install (no docker container) running on Centos Streaming for years no isue.

Can I reinstall and preserve all my cache settings?
confirmed my plex repo and tried a yum reinstall plexmediaserver

still not listening on the web
same error.

tried renaming :
/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Preferences.xml" to bak and restart

Now it is listening on 32400

But still can’t reach on web:
image

How do I get in contact with a Dev to reinstall the App Supp setup?

Doesn’t show TCP4 running.

What is the status of your firewalld sudo firewall-cmd --state

  1. tcp6 is the combined TCP v4 and TCP v6 socket.
  2. Are the logs being written to? (/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Logs)
  3. Perform a ls -la on the Plex Media Server directory and attach here please.

Thank you.
I was able to fix it with a reinstall.:

yum reinstall plexmediaserver
cd “/var/lib/plexmediaserver/Library/Application Support/Plex Media Server”
mv Preferences.xml Preferences.xml.bak
