no problem, I've been testing all other stream services, happy to help,

I tested the hls stream again after your change.

The good news, my web player can now request the manifest, so cors is definitely working.

However, I’m seeing a few new issues when streaming from OBS,

The stream comes online, then drops offline

Sometimes it appears in the player for a moment, then the player reports the stream as offline again. A few seconds later it may come back, then drop again.

hls buffer append error & Autoplay failed: DOMException: The fetching process for the media resource was aborted

hls buffer append error

It looks like the manifest loads correctly, but some of the .ts segments might be failing intermittently, which triggers hls . js to treat the stream as broken and drop back to “offline.”

summary

OBS to Simulcast detects “stream online”

Player starts loading segments

Buffer append fails intermittently

hls . js recovers - fails - recovers - fails

(stream flickers online/offline)
