hello, she has a gigabit connection , and my upload speed is fast enough to deal with it but for some reason she has 8/10 times constant issues where it buffers every second ,whether with directplay or transcoding (i can transcode at 6x the framerate of the shows so shouldnt be an issue)

can anyone recommend a way to speed up or solve this issue? it wasnt a problem till i had to reinstall jellyfin and i believe i have put all the settings back to how they were.

is there an alternative to tailscale , that is still free and maybe faster without any issues such as relaying
