Remote import failed
A catch‑all on the Remote URL tab when the NDJSON stream sends an error event without a usable message string. Most real failures show a more specific line (timeout, size, S3, DNS, and so on).
Why this happens
The client expects each error line to include a human message. If the stream is truncated, proxied oddly, or the payload is malformed, you only get this generic text. Server-side import failures normally pass a concrete reason through runMemberRemoteUrlImport.
Diagnose and fix
1. Open DevTools → Network → from-url and read the NDJSON lines for a specific message.
2. Check app logs around runMemberRemoteUrlImport / storage write for the same timestamp.
3. Confirm Remote URL mod on, tier not blocked, uploads enabled, and storage node healthy.
4. Retry a small direct https:// URL. If you get a clearer message, follow that article instead (timeout, max size, S3, and so on).
