After a CPU-heavy AE render+transcode the orchestrator/DB can be briefly slow; the 15s client timeout made the post-render output-upload-url call fail and the finished MP4 was dropped (completed without export). Bumped client timeout to 60s and retry the upload-URL call up to 4× with backoff so a finished render's output is never lost to a transient stall.
