Your page has a robots meta tag or X-Robots-Tag header with “noindex”, or a Disallow rule in robots.txt matches it. Google then won't show the page. Remove it if the page should be found.

Some sites answer automated checks with 403 or 429 even though the link works in a browser. We show those separately so you can focus on real errors like 404 and 500.
