What is the issue you’re encountering

I’m using Cloudflare Load Balancing but I can’t seem to fetch client IP address via X-Forwarded-IP or CF-Connecting-IP request header.

What steps have you taken to resolve the issue?

I’ve added X-Forwarded-IP and CF-Connecting-IP request header to nginx access log, but it appears as ‘-’

Here’s my log_format setting:

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for" "$http_cf_connecting_ip"';

This request is being made by one of Cloudflare crawler. I assume that the reason you see the CF-Connecting-IP as -. What if the request being made by the real user via the load balancer ?
