The startup configuration only reads JELLYFIN_ prefixed environment variables, so the bare Jellyfin__TranscodeStore__* form used by the chart, the manifests and the README is dropped and the Redis store is never registered. Nothing logs the selected store, so the fallback is invisible. - Read bare Jellyfin__* variables into the Jellyfin:* configuration root - Keep an explicit JELLYFIN_ variable winning over the bare form - Log the selected transcode session store at startup - Ping Redis once at startup and log an unreachable store at Error - Log endpoints only, never the connection string
