The URL is declared in robots.txt but does not return a successful response.

Consequence. Crawlers find nothing at the address they were pointed to, so no URLs are submitted. This is worse than declaring no sitemap, because the declaration suggests discovery is covered when it is not.

If that is not intended. Publish the sitemap at the declared URL, or correct the URL to where it lives.
