ERR_TOO_MANY_REDIRECTS means the browser is being redirected repeatedly and never reaches the final page. Adding more redirect rules usually makes this worse.
Start with HTTPS consistency
Confirm WordPress Address and Site Address use the intended https:// URL. Hostinger recommends HTTPS for WordPress and documents the normal configuration in its force HTTPS guide.
Check for two systems forcing the same redirect
A hosting redirect, WordPress/plugin redirect, CDN/proxy rule and manual .htaccess rule can conflict. Review one layer at a time rather than disabling security globally.
If Hostinger CDN is enabled
Hostinger notes that redirect loops can occur when another proxy/CDN is active at the same time or when manual redirect rules conflict with HTTPS. Its current CDN troubleshooting guide recommends isolating the CDN to identify the source.
Clear cache after correcting the cause
Only purge caches after the configuration is consistent. Clearing cache cannot fix a redirect rule that is still wrong. See our Hostinger and WordPress cache guide.
Do not remove SSL as a first fix
Hostinger maintains a dedicated SSL troubleshooting section. Preserve HTTPS and correct the conflicting configuration wherever possible.
Verification
Test the exact URL in a private browser window. It should make at most the expected canonical redirect—for example HTTP to HTTPS—and then load normally.
