The browser gave up after being redirected in a circle.
THE CAUSE
Two or more redirect mechanisms pointing at each other.
THE COMBINATIONS THAT CAUSE IT
cPanel Force HTTPS plus an .htaccess rule plus a plugin setting Cloudflare set to Flexible, requesting http from the server while serving https, with the server redirecting back A www redirect and a non-www redirect in opposition The application's site URL set to http while a redirect forces https
DIAGNOSING
- Disable every redirect you can find: the cPanel toggle, plugin SSL options, and
.htaccessrules. - Confirm the site loads.
- Enable one method only and test.
THE CLOUDFLARE FIX
Set SSL/TLS to Full (strict). This resolves most Cloudflare loops in seconds.
THE WORDPRESS CHECK
Settings > General. If the site URL is http and a redirect forces https, they will fight indefinitely. If you cannot reach the admin, define WP_HOME and WP_SITEURL in wp-config.php.
TESTING
Always in a private window. Browsers cache redirects and keep showing the loop after it is fixed.
