Manifest and playlist structure
Check whether the top-level playlist loads, then determine whether a child playlist or segment is failing.
CORS and browser security
A browser cannot override CORS, authentication, referrer, IP or geographic restrictions.
403 / 404
403 often indicates authorization or token problems; 404 means a requested resource was not found.
HTTPS and codecs
Use HTTPS resources on an HTTPS page. Codec support can still block playback.
Live vs VOD
Live playlists update continuously; VOD playlists normally remain stable.
