Same path as me, my issue was nginx wasn’t configured to take the docker IP as a range to set the realip on.
set_real_ip_from 172.18.0.0/16;
real_ip_header X-Forwarded-For;
real_ip_recursive on;
set_real_ip_from 172.18.0.0/16;
So i go User > Cloudflare > Server Nginx (SWAG Docker) > Discourse
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Proto https;
proxy_set_header X-Forwarded-Ssl on;
proxy_set_header X-Real-IP $remote_addr;
