Error message

failed to fetch the post, the page might be "private", or the link is completely wrong

What it means

The instagram extractor tries several embed-based methods (embed endpoint, GraphQL shapes, embedded-image fallback) to locate media URLs; this error is raised only after all of them returned nothing. As the message states, the post is most likely private, deleted, or the link is wrong — it is a last-resort aggregate failure.

Solutions

1. Open the link in an incognito browser — if it does not render logged-out, the extractor cannot see it either.
2. Normalize the link to the canonical https://www.instagram.com/p/<code>/ form.
3. Move to a residential IP or an authorized session; anonymous scraping is heavily throttled.
4. If the page renders fine logged-out, diff the embed HTML and update the extractor's matchers.

func isInstagramFetchFailed(err error) bool {
	return err != nil && strings.Contains(err.Error(), "failed to fetch the post")
}

Catch, record the short code, and skip — private or deleted media has no programmatic remedy without an authorized session. Do not hammer retries; Instagram throttles aggressively.

When it happens

Trigger: Private-account posts; deleted or deactivated media; malformed links; Instagram serving login walls to server IPs so every embed method comes back empty.

Common situations: Scraping from datacenter IPs; links copied from DMs or stories that require login; format changes to the embed HTML.
