Media never becomes ready

Check the file format, media-worker status, Redis connection, S3-compatible storage, and the required native binary: FFmpeg for video, Poppler for PDF, or LibreOffice for presentations. Search worker logs by media identifier.

Screen remains pending

Confirm that the pairing code had not expired, find the new request under Écrans, and provide its required name, location, and channel before approval. Reload /display if the device is slow to update.

Screen displays no content

Check, in order:

1. the screen is active and assigned to the expected channel
2. the channel has a valid template
3. a schedule is active at the current channel-local time
4. the selected playlist contains ready, active media
5. the device can reach the application and signed object-storage URLs
6. system clocks and the channel timezone are correct.

Wrong playlist is displayed

Look for a higher-priority event or recurring schedule, then verify the channel timezone. Correct conflicting rules instead of modifying the fallback playlist.

Widget is empty

Validate its city, feed URL, provider, stop identifiers, and server-side network access. Check provider rate limits and application logs.
