Library scanning looking for old location

[Space12]

In my jellyfin server setup, the media is stored on a remote network location (different vlan, but still local gig/multi-gig connected).  for the sake of this,  Jellyfin ip: 192.168.1.12  - original media location 192.168.2.10\media.  this has worked perfect.

After a hardware upgrade, the media location moved to 192.168.2.11\media

I updated the library location and everything is working, the old media host is now gone/off the network.   in the jellyfin server logs, daily, I see the media scan task go out and look etc.  no error no issues
However, in my firewall logs within a minute of the media scan, I also see an IP "attempt" to the old IP address   1) it's blocked but more important 2) it's not there anymore.

every 24 hours this happens,  a good media scan and with no errors in the logs and see an attempt at nearly the same time to the old IP.
I have looked everywhere and I am stuck.
In the GUI there is zero mention of the old IP (192.168.2.10)  the Library is only set to the new IP.

Where else can I look, it feels like there is an old pointer/config that is "stuck"

Check playlists for the old path. Playlists use absolute paths and are not dynamically updated.

That did not help as well as setting deubg for logging did not show any errors. Since I really could not prove it was an app issue and not the OS, I decided to do a new VM, new app install and start over. Since then the errors have gone away.
