It looks like the MIME type of your stream is incorrect. It’s showing up as application/octet-stream when it should be application/vnd.apple.mpegurl. This is also causing the .m3u8 file to download when accessing the URL directly in Safari, when it should playback since HLS is natively supported in Safari.
Please let me know if you need any more help or have any other questions.
