I updated to the latest server yesterday, after that access to web (:32400) does not work any longer (404 Not found).
Tried to restart the server as well as re-install the package to no success.
Streaming on clients works without any problems.
Server Version#: PlexMediaServer-1.22.3.4392-d7c624def-x86_64.qpkg
Player Version#: N/A
Found in a Plex Media Server log file;

I am assuming it is related. But nothing has changed on my QNAP since at least a couple of days…
Maybe reboot the device? It implies something else is running and using the ports we bind to (32400)
Managed to reboot and it works fine now. Thanks.
I’ve had this same issue on my last two updates of PMS on my QNAP device.
After updating PMS in the App Center, the service shows as running but is not accessible and when looking in the logs I see the error message above in the original post.
I have then attempted to stop and start the service via the App Center and this still does not resolve the issue.
When investigating further via SSH, even when the service shows stopped I can still see the process binding to the port using netstat:
[~] # netstat -lpn | grep 32400
tcp 26 0 :::32400 :::* LISTEN 29322/Plex Media Se
After killing this PID, I am able to restart PMS without any issues.
I suspect something has changed in the update script that results in the previous version not stopping correctly.
