HLS troubleshooting
An HLS playlist opens as text but a player rejects it
Check the first line before testing media, network speed or player settings.

Reproduce the condition
The HLS sample below is a small synthetic file. It carries no active media source or account data.
# An illustrative file
#EXTINF:4,
segment-1.tsWhat the local check found
| Expected signal | Observed signal |
|---|---|
| Missing EXTM3U header | Missing EXTM3U header |
What to do next
Use the actual playlist output from the authorized source. A list of segment names alone is insufficient for an HLS player.
What to share if the problem continues
- The exact parser result and version of the importer or player.
- A minimal redacted sample with dates, IDs or segment names retained as needed.
- The output after checking the source export separately from the viewer app.
