 * Hello,
 * I am fresh with Cloudfare, and the test cache is always failed. Here is test 
   process:
 * 1# Add domain on cloudflare with free try.
 * 2# We create site with SSL with **Let’s Encrypt** by following post at [https://docs.wordops.net/how-to/configure-letsencrypt-dns-api-validation/](https://docs.wordops.net/how-to/configure-letsencrypt-dns-api-validation/)
 * 3# On Cloudflare, we set SSL/TLS as Full, otherwise, the site will unaccessible
   both for backend and frontend if this plugin is activated, and it will show “**
   This page isn’t working right now**” and **ERR_TOO_MANY_REDIRECTS** even if we
   access site with /?swcfpc=1, and here is screenshot at [https://prnt.sc/ypb2VVw_-6pt](https://prnt.sc/ypb2VVw_-6pt).
 * “Purge everything” did not fixed the it.
 * 4# On [Super Page Cache for Cloudflare](https://wordpress.org/plugins/wp-cloudflare-page-cache/),
   we use all default setting.
 * 5# On our server, we use Nginx **fastcgi_cache** and Nginx helper on wordpress.
 * Issue please:
 * 1# In this case, when “Test Cache” will be failed and reset plugin setting does
   not fixed it, and please check the screenshot: [https://prnt.sc/mvtvpYk6tG-v](https://prnt.sc/mvtvpYk6tG-v)
 * 2# In response header, it show

 * Hi [@alexliii](https://wordpress.org/support/users/alexliii/),
   Can you please
   let me know your website address? Also in terms of fixing the too many redirects,
   try setting the SSL type inside Cloudflare account as Full Strict. Also Inside
   Cloudflare settings page disable the always use HTTPS option. Once you play with
   these options, you get to see which setting is actually causing the too many 
   redirect option. It is not this plugin that is causing this, but moreover it 
   might be a bad settings that is causing this issue.

 * This issue seems that it need take time to be valid for Cloudflare although they
   officially claim the setting will be vaild after 30 seconds, but, actually it
   vary a lot.
 * I am in China, and the server is in California US on Digitalcean.
 * For now, I enabled Always Use HTTPS, and the test cache is working too.
 * It seems that if cf-cache-status show up in the response header, then the test
   cache will pass, am I right?
 * Thanks

 * hi [@alexliii](https://wordpress.org/support/users/alexliii/),
   yes it should 
   but the best way to test is by checking the actual response header.
