CloudFlare too many redirects on proxied domain ​

If you've switched DNS to CloudFlare and you're noticing that your site fails to load when you enable the proxy and reports something like "Too many redirects" then you should just need a small configuration change. You probably have to switch your SSL/TLS option from "Automatic SSL/TLS (default)" to "Custom SSL/TLS" and then switch from "Flexible" to "Full (strict)".

If you don't have a "real" certificate for your backend server you may need to choose "Full" instead of "Full (strict)".

Step 1: Go to SSL/TLS overview for your domain ​
