Reducing buffering when accessing Jellyfin via Tailscale (lemmy.world)

I currently have a jellyfin setup running on my pc which I access when away from home by tailscaling into my home network. This works great for my partner and I while we are away from home.

I have given my siblings access to my jellyfin setup as well, and I've added them to the tailscale network too. They live in a different country though and have had some latency issues (media buffering constantly) making it kinda suck to use.

I would love to be able to improve this performance but I dont really know where to start. Would this be a bandwidth issue somewhere between my pc, tailscale, my router, their router, and their device? Would this be caused by some setting in my jellyfin setup or in the jellyfin client on their device? I would really appreciate any advice on where I should start to troubleshoot to improve this performance.

Tailscale can use relays if it cant find a way to make a p2p connection. Check the documentation. There is a command you can run to see whats using the relay.

The siblings could run
tailscale ping nodeIP/nodeName
This not only shows if they are connected via a DERP (relay) but also retries to connect them directly a few times.
If that doesn't work out it can sadly be quite hard figuring out why a DERP is used instead of a direct connection.

This is the first thing I'd look at too.
