Is there a section in your discourse.conf
that tells it to set_real_ip

from: "types {"
to: |
set_real_ip_from 192.168.1.0/24;
set_real_ip_from 172.18.0.0/24;
set_real_ip_from 172.17.0.0/24;
set_real_ip_from <SOME_IP_V6_ADDRESS_THING_HERE?>
real_ip_recursive on;
real_ip_header X-Forwarded-For;
types {
