Playback crash a lot

[34626]

Hi all,
Im trying to play movies to my Raspberry pi 4 (has USB SSD) and LibreElec nightly from 30. september 2025.
I have added the Jellyfin repo and installed JellyCon 0.8.3
Its all connected with lan cables (I have ordered new once (cat 8.1) if the issue is electrical noise, got a lot of electronics running there.
But, when i play 1080p content the playback will stop very often and only thing shown in log is this:
[2025-10-08 14:29:04.413 +02:00] [INF] [54] Emby.Server.Implementations.Session.SessionManager: Playback stopped reported by app "Kodi JellyCon" "0.8.3 py3" playing "Transformers One". Stopped at "814382" ms

I use Jellyfin 10.11 (latest release candidate) which actually helped a bit vs 10.10.7

I only use IPv6 (locally and outside home)
but the issue only is on this client (i have two)

I wonder if its a bug in JellyCon 0.8.3, because the Raspberry pi dosent sweat over the playback), so i hope someone in here maby have same issue?
