Constant Install Issues

[use7]

I unfortunately am unsure why your user would become unrecognized, possibly someone else here uses windows and sees/knows something that I'm missing.  In terms of other things though in order to get your lan recognized you have to put it into the field in the dashbord (Dashbord -> Networking [under the 'advanced' secton on the sidebar] -> LAN networks and you'll want to fill in your address space, e.g. 192.168.1.0/255.255.0.0 for many routers, may be something like 127.0.0.0/255.255.0.0 for internal or 10.0.0.0/etc. depending on how your network has been set up).

Looking at the file log_20230902.log I see that you loose your login token and then see that your user is unrecognized:

Code:

[2023-09-02 08:19:02.644 -04:00] [INF] [68] Jellyfin.Api.Auth.CustomAuthenticationHandler: "CustomAuthentication" was not authenticated. Failure message: "Invalid token."

and then (

Code:

[2023-09-02 08:19:05.593 -04:00] [ERR] [105] Jellyfin.Server.Implementations.Users.UserManager: Error authenticating with provider "Default"

MediaBrowser.Controller.Authentication.AuthenticationException: Specified user does not exist.

I'm not positive what may be causing this, but my knee-jerk reaction would be that an antiviral (or windows optimization/etc.) may be 'cleaning' out the JF user database causing this problem?  I think the default location for saving data is C:\ProgramData\Jellyfin\Server; you may want to look through any Windows logs/antiviral logs to see if that file path is brought up at all?  This also may be a red herring since you said that you've reinstalled the server and then this failed; so if you tried to reinstall and didn't set up your users again JF wouldn't recognize your username and would result in this issue. 

For the failing to boot you can try to look through the Windows event manager and/or turn on debugging logging in JF (https://jellyfin.org/docs/general/admini...eshooting/) and see if there's any smoking gun in the log files.
