After you add a new domain to Cloudflare, your visitors' browsers might display ERR_TOO_MANY_REDIRECTS or The page isn’t redirecting properly errors.
This error occurs when visitors get stuck in a redirect loop.

This error is commonly caused by:
- A misconfiguration of your SSL/TLS Encryption mode.
- Various settings in SSL/TLS > Edge Certificates.
- A misconfigured redirect rule.
{{
}}For assistance determining if your origin web server is responding with redirects, contact your hosting provider or site administrator.
{{
}}Your domain's SSL/TLS Encryption mode controls how Cloudflare connects to your origin server and how SSL certificates presented by your origin will be validated.
This setting can cause redirect loops when the value you set in Cloudflare conflicts with the settings at your origin web server.
If your domain's encryption mode is set to Flexible, Cloudflare sends unencrypted requests to your origin server over HTTP.
Redirect loops will occur if your origin server automatically redirects all HTTP requests to HTTPS.

end
To solve this issue, either remove HTTPS redirects from your origin server or update your SSL/TLS Encryption Mode to be Full or higher (requires an SSL certificate configured at your origin server).
If your domain's encryption mode is set to Full or Full (strict), Cloudflare sends encrypted requests to your origin server over HTTPS.
Redirect loops will occur if your origin server automatically redirects all HTTPS requests to HTTP.

To solve this issue, remove HTTP redirects from your origin server.
If you have Always Use HTTPS enabled for your domain, Cloudflare redirects all http requests to https for all subdomains and hosts in your application.
Redirect loops will occur if your origin server automatically redirects all HTTPS requests to HTTP.

To solve this issue, remove HTTPS redirects from your origin server or disable Always Use HTTPS.
If you have HTTP Strict Transport Security (HSTS) enabled for your domain, Cloudflare directs compliant web browsers to transform http links to https links.
Redirect loops will occur if your origin server automatically redirects all HTTPS requests to HTTP or if you have your domain's encryption mode set to Off.

To solve this issue, remove HTTPS redirects from your origin server and make sure your domain's encryption mode is Flexible or higher.
Alternatively, disable HTTP Strict Transport Security (HSTS).
Redirect loops can also occur if you have conflicting URL redirects.

To solve this issue, review your various redirect rules and Page Rules (deprecated) to make sure no rules are not in conflict with each other.
{{
}}To reduce the potential for redirect loops and mixed content errors, Cloudflare recommends WordPress users to install the Cloudflare WordPress plugin at their origin web server and enable the Automatic HTTPS rewrites option within the plugin. Alternatively, Cloudflare recommends the SSL insecure content fixer or Really Simple SSL plugin.
