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.

Sames, I have a bunch of users(2) all streaming jellyfin fine over tailscale, except one house which buffers sporadically over the day. There's no rhyme or reason to the when, or the what that needs to be buffered. As in it'll buffer direct plays/HEVCs/AV1s, or it'll play them fine. Some times it'll buffer at night, sometimes during the day, sometimes neither or both. Worse, I'm getting all my information via users, so maybe theres a common thread, but they haven't found it.

Their internet speed is fine. It could be WiFi being saturated in their area. It could be the relay being a very old rPi3 just isn't up to it (The pi, captures their requests through Pi-Hole and proxyies their traffic over tailscale). It could be the laptop they're using as a client isn't up to it. Or it could be some setting somewhere.

It's annoying whatever it is.
