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.

  1. You might want to set an appropriate bitrate and video quality for transcoding for these users that works acceptably for their latency and bandwidth.
  2. The reason netflix, prime, Disney+, etc work as well as they do is because they have CDN peering, so your version of Game of Thrones comes from somewhere much closer to you in a network sense. You can change your tailscale relay, or you can lock down jellyfin to their ip and specific port and skip the tailscale (I don't recommend it unless you know what you're doing) and let routing tables help with latency.
