Clearing HSTS settings to fix a "Too many redirects" Page report error

Modified on: Wed, 17 Nov, 2021 at 9:22 AM

A "Too many redirects" error can occur when you are loading a Page report for an “HTTP” page that has HTTP Strict Transport Security (HSTS) enabled.  HSTS is a web security policy mechanism that helps to protect websites from attack.

The Page report environment attempts to redirect from HTTPS to HTTP, but if the original page has HSTS enabled, then the browser will automatically re-redirect the user back to HTTPS, causing an infinite loop.

The browser sees this and responds with a "Too many redirects" error.
