No redirect loop

What the check finds

The redirects loop, so the page never resolves.

A loop never reaches a page, so search engines and AI crawlers get nothing to read or cite. Browsers stop with an error too.

Trace the hops with curl -IL or a redirect checker to find where the loop starts.
Fix the conflicting rules, often http vs https or trailing slash rules that undo each other.
Make the final URL return 200 and point every redirect straight at it.
