Yeah I believe you’re right… when I tried to playback eLeague I’d occasionally get a blip of audio/video into instant failure (sometimes just failure)… this occurs on my TV, my Web browser on my PC (Through plex twitch channel) as well as on my LG 4K smart tv using plex + twitch channel…
All of these devices are capable of playing other twitch streams through plex (no transcoding) otherwise… I really don’'t get why this one stream in particular doesn’t work.
