Description of the bug

I just upgraded to 10.10.7 and started getting the following on startup:

[2025-05-12 17:08:53.452 +01:00] [ERR] [1] Main: Kestrel failed to start! This is most likely due to an invalid address or port bind - correct your bind configuration in network.xml and try again
[2025-05-12 17:08:53.455 +01:00] [FTL] [1] Main: Error while starting server
System.IO.IOException: Failed to bind to address http://0.0.0.0:8096: address already in use.

What's even weirder...the UI to access Jellyfin and the Jellyfin Console works fine.

The network.xml file I'm using is this:

`

<?xml version="1.0" encoding="utf-8"?> false false 8090 8920 8096 8926 false false true false true true veth false false `

Any recommendations would be great.

:)

Reproduction steps

  1. Click "Jellyfin (View Console)"
  2. Observe startup process
  3. Windows closes after error

What is the current bug behavior?

The console crashes when the error occurs

What is the expected correct behavior?

Console not to crash

Jellyfin Server version

10.10.0+
