NginX Proxy Manager behind XG

got a similar setup 

XG waf -> Nginx -> Website

On my website i can find the real ip by reading using the header x-forwarded-for.

As you are asking for the real ip in the reverse proxy maybe you can check if you can read this header out on nginx as well.

I'll check such option NginXmanager. 

So for me it didnt work ;/ once i have had website behind Cloudflare so it was:

Cloudflare -> XD[DNAT]--->NginX--->Host and i was able to config my website to pass origin ip source. with this syntax: 

set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 104.16.0.0/12;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 131.0.72.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 172.64.0.0/13;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 188.114.96.0/20;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 2400:cb00::/32;
set_real_ip_from 2606:4700::/32;
set_real_ip_from 2803:f800::/32;
set_real_ip_from 2405:b500::/32;
set_real_ip_from 2405:8100::/32;
set_real_ip_from 2c0f:f248::/32;
set_real_ip_from 2a06:98c0::/29;
real_ip_header CF-Connecting-IP;

but i dont use CF anymore so i was tryied as you suggest:
real_ip_header X-Forwarded-For;


but now luck
