TROUBLESHOOTING NOTE
Redirect loops: find the repeating hop before changing rules
Updated
A redirect loop sends a request back to a URL it has already visited. A browser may report too many redirects. The useful starting point is the observed chain, rather than changing several settings at once.
Capture the URL and chain
Enter the affected public URL in the redirect checker, including its path. Compare the hops and HTTP status codes. An A → B → A pattern identifies the URLs to investigate. A chain exceeding this tool's five-hop limit is not necessarily a loop.
Download the report before changing settings so you can compare the before and after results. Never submit URLs containing login tokens or other secrets.
Find the conflicting rule
Look for HTTP/HTTPS or www/non-www alternation. Compare redirect settings at the CDN, hosting platform, web server and application. A proxy and origin can disagree about the original scheme. Use your provider's documentation to identify the correct configuration rather than disabling HTTPS as a workaround.
Choose one intended destination and adjust the conflicting rule in a controlled change. Test in staging or retain a rollback plan. Avoid changing several layers simultaneously, because that hides which change resolved the problem.
Recheck more than the homepage
Repeat the check on the affected path and other important pages. Confirm that the final destination returns the expected response. Review permanent versus temporary redirects according to whether the move is lasting.
This checker follows HTTP redirects only. If it sees no loop but the browser still fails, investigate cookies, authentication, JavaScript and meta-refresh behavior separately. A corrected HTTP chain does not prove the entire application works.
