Jellyfin on WebOS - slow performance

[DrWombat]

Data is on Synology 918+, Docker installation, SSD Cache enabled
When I start the Jellyfin client in WebOS (LG G39), it takes quite a long time until the film images are loaded from the database.
However, if I start Jellyfin via the rudimentary web browser within WebOS, it goes much faster.
Then the performance is just as good as with the Windows client on my PC, for example.
So it can't be the LG TV hardware who is limiting the performance.
Any explanation or solution?

Can you share your full jellyfin logs via pastebin?

[DrWombat]

Sure, but never done before.
Is there an explanation available how to do this?
Thanks!

In the Jellyfin UI go to Dashboard > Logs. The latest log file should be at the top of the list (file name log_<insert date>.log), click on it, select all, and then copy and paste into pastebin.com. Once you save on pastebin it will give you a URL.

I looked at the log file and found the solution:.
I have set up guest access named LG_TV with limited rights for the LG TV (so that someone cannot accidentally cause damage to the server).
When I logged in with this, the log file says a DLNA connection has been set up but the http connection has been refused:

[2024-07-19 16:45:48.743 +02:00] [INF] [44] Emby.Server.Implementations.HttpServer.WebSocketManager: WS "192.168.178.29" request

I deleted the Guest Account and created a new one and received the following:

[2024-07-19 17:32:07.436 +02:00] [INF] [29] Jellyfin.Server.Implementations.Users.UserManager: Authentication request for "LG_TV" has succeeded.
[2024-07-19 17:32:07.436 +02:00] [INF] [29] Emby.Server.Implementations.Session.SessionManager: Current/Max sessions for user "LG_TV": 0/0

Now it's much faster again
