​

Why

​

Failure response

{
  "error": {
    "code": "preflight_failed",
    "rule": "pinterest.cover_image_url.reachable",
    "platform": "pinterest",
    "message": "URL returned 404: https://cdn.example.com/cover.jpg",
    "remediation": "Pinterest must be able to fetch the cover image URL; verify it is public and returns 2xx."
  }
}

​

Remediation

• Verify the URL is publicly reachable from outside your network (no auth, no IP allowlist).
• Don’t use Google Drive share links, Dropbox preview URLs, or signed S3 URLs that have expired — same general failure mode as instagram.media.reachable (OAuthException 2207052).
• When in doubt, upload the cover via POST /v1/media and use the returned public URL.
