image.unreachable
Image URL could not be reached. Level: Warning.
When it is raised
Raised when the API's crawler gets no HTTP status for the image: the connection is refused or fails (including a TLS failure), a request gets no response within 4 seconds, the 6.5-second budget shared by the page and image requests runs out, the response body sends no bytes within 4 seconds, the request is redirected 8 or more times, or a redirect leads to a URL that is not http or https.
What it does to a shared link
No image was received, so no image dimensions, size or crop are measured and the image checks that depend on a loaded image do not run. The API still requests robots.txt from the image host, because that file is fetched separately; the robots.txt checks report nothing if it cannot be fetched either.
How to fix it
- Request the image URL from outside your network and confirm it responds within a few seconds.
- Check that the image host accepts https connections and has a valid certificate.
- Remove redirect chains by pointing the tag straight at the image's final URL.
- Run the check again to rule out a temporary network fault.
