Remote download timed out
The site stopped waiting for the remote origin while downloading the file for import. The hard timeout is about 30 minutes.
Why this happens
Remote URL import aborts the outbound fetch when REMOTE_IMPORT_DOWNLOAD_TIMEOUT_MS elapses. Slow origins, very large files, flaky networks, or a low Remote upload speed cap for the tier can push the transfer past that window.
Diagnose and fix
1. Member: try a faster direct link, a smaller file, or upload via browser / SFTP instead.
2. Admin → Settings → Users & limits → Remote upload speed (ul2_remote_up_kbs_*) — a very low Kbytes/sec cap makes timeouts more likely; raise it if the business allows.
3. Confirm the origin responds quickly from the app server (curl -I / timed download sample).
4. Check proxy timeouts are not shorter than the import window on /api/upload/from-url.
5. The 30‑minute limit is a product constant — not a Users & limits toggle.
