M3U8 404 Not Found: Causes and Solutions
Fix M3U8 404 errors when playing or downloading HLS streams. Learn why segments go missing and how to recover broken streams.
What Causes M3U8 404 Errors?
A 404 means the server can't find the resource. This can happen for: the master playlist (wrong URL), media playlists (missing variant), TS segments (expired or removed), or encryption keys (missing key file).
Segment Expiration for Live Streams
Live HLS segments have a limited lifespan. Once outside the playlist's sliding window, the server may delete them. If a player requests an expired segment, it gets a 404. This is normal for live streams.
How to Diagnose
- Open the M3U8 URL directly — 404 means the playlist is gone
- If the playlist loads, try visiting a segment URL directly
- Check relative paths — the player may be looking in the wrong directory
