Cloudflare and nginx: Too many redirects

Question

I'm trying to set up NGINX and cloudflare. I've read about this on Google but nothing solved my problem. My cloudflare is active at the moment. I removed all page rules in cloudflare but before had domain.com and www.domain.com to use HTTPS. I thought this could be causing the problem so I removed it. Here is my default NGINX file, with purpose of allowing only access by domain name and forbid access by IP value of the website:

server{    #REDIRECT HTTP TO HTTPS    listen 80 default;   listen [::]:80 default ipv6only=on; ## listen for ipv6   rewrite ^ https://$host$request_uri? permanent;  }  server{    #REDIRECT IP HTTPS TO DOMAIN HTTPS             listen 443;     server_name numeric_ip;     rewrite ^ https://www.domain.com;   }  server{    #REDIRECT IP HTTP TO DOMAIN HTTPS      listen 80;     server_name numeric_ip;     rewrite ^ https://www.domain.com;  }  server {           listen 443 ssl;          server_name www.domain.com domain.com;          #rewrite ^ https://$host$request_uri? permanent;          keepalive_timeout 70;           ssl_certificate     /ssl/is/working.crt;          ssl_certificate_key /ssl/is/working.key;           ssl_session_timeout 1d;          ssl_session_cache shared:SSL:50m;           #ssl_dhparam /path/to/dhparam.pem;           ssl_protocols TLSv1 TLSv1.1 TLSv1.2;          ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM$          ssl_prefer_server_ciphers on;           add_header Strict-Transport-Security max-age=15768000;           (...) more ssl configs 

What could be off? I'll provide mroe information if needed...

Answer 1

After tryouts I found that this is only related to Cloudflare. Because I had no redirect problem before moving to Cloudflare.

In my case it was a simple fix like this. Select [Crypto] box and select Full (strict) as in the image.

Really, you can try this out first before any other actions.
