Can't play m38u files

[gartiol]

These are files that are online on the web and publicly accessible. I have tried to create strm files with links to the online source file (m38u). But when I try to play that file with Jyllyfin, Jellyfin will not play the best version/resolution of the file (1920x1080). Jellyfin will only play the first version listed (640x360) in the m3u8.
