Too many remote uploads
POST /api/upload/from-url returned a rate limit: too many remote imports for this user/IP in the current window (default about 300/hour).
Why this happens
App (and often nginx) throttle remote leech requests. Pasting huge URL lists or automation burns the hourly budget. Member API remote URL may use a slightly different “remote URL upload requests” message and its own bucket.
Diagnose and fix
1. Member: wait and retry later; split large URL lists across time.
2. Admin → Settings → Mods — upload_source_remote_url_rate_per_hour (see Remote URL rate limit).
3. Regenerate/reload nginx upload rate snippets if you use them after changing Mods rates.
4. Confirm they are not blocked by plan (Block remote URL upload) — that is a different message.
