Jellyfin never working right via Browser

[widardd]

Hey there,

First of all here's my devices that are trying to stream to:

At home on LAN/WLAN

SeriesS
PS4
PC Windows
PC Linux
Smartphone Android
Tablet Android

Outside my home via 40mbit upstream, never more than 1080p at 10mbps:

Smartphone Android
Tablet Android
Laptop Windows
FireTV
SmartTV

Now here's my issue regardless of quality and Platform or at Home or one the Go, jellyfin Just keeps on buffering with only a few Breaks here and there If I try to Stream via Browser.

Dropping quality doesn't do anything, and when I ssh into my server, I can see it being idle, just waiting for the client.

The moment I usw the App instead where that is possible, Android, SmartTV, Linux, Windows.. All issues are gone and I can stream flawlessly. The one exceptipn is the Xbox App, which got the same issues. But that one is deprecated.

The Media I am trying to Stream is just the average 1080p h264 DD MKV.

My Server ist a thinkcentre m600 which ist able to support 4 transcoding clients at a time without issues.

Any help would be greatly appreciated!

Which browser? Are you using a reverse proxy? Can you open the dev console in your browser and make not of any errors that appear around when it buffers?
