/health not found - filling logs

[JamesTX10 7]

I was looking at the log file to review something else and see that I have a 404 error every 30 seconds

2025-10-21 00:00:29.249 Info Server-0HNGG4CFL03EP:00000001: http/1.1 Response 404 to ::1. Time: 0ms. GET http://localhost:8096/health.

What is the cause and how do I resolve?

Hi, the server has no such api named /health.

You must have something on your server machine sending out those requests. You will need to find out what it is and shut it down.

Any ideas on how to track that down?

[Luke 42077]

If you temporarily enable debug logging, then you will see the request headers that it is sending, and that might have some clues in it.

Here is what that added

I would start shouting down software on the server machine until they go away.

I would suspect it is some plugin doing it and mistakenly polling an endpoint meant for a different server platform.

You nailed it. I run Jellyfin in docker and configured it to use a different port BUT the health check URL was not updated. Changed that URL to have the correct port and no more errors in my Emby Logs. THANKS
