I've updated our Nginx Proxy Manager docs recently.

https://jellyfin.org/docs/general/networ...xy-manager

Double check your setup lines up with our docs. If it does, we can do some additional troubleshooting.

Hello!
I have the same problem.
My computer is running on Proxmox with an OpenMediaVault VM. It contains a Docker container for Jellyfin. Everything works fine, but I keep getting the same error messages, namely three lines:

Code:

[18:10:04] [INF] [21] Jellyfin.Api.Auth.CustomAuthenticationHandler: CustomAuthentication was not authenticated. Failure message: Invalid token.
[18:10:04] [INF] [21] Jellyfin.Api.Auth.CustomAuthenticationHandler: CustomAuthentication was not authenticated. Failure message: Invalid token.
[18:10:04] [INF] [21] Jellyfin.Api.Auth.CustomAuthenticationHandler: AuthenticationScheme: CustomAuthentication was challenged.

My Nginx Proxy Manager is configured as described in the documentation. But when I disable the proxy host or quit NPM, the error persists.
The debug log also doesn't provide any clues as to the source of the error. An IP or hostname would be helpful.
Can someone please help me? I'm running out of ideas.

This is unrelated to Nginx. This is likely a TV client, Android TV or Roku, that has an expired authentication token. You need to find the offending client and log out and log back in on that TV client.

THX, had found the issue. It was an abandoned Home assistant Container
