    Code:
    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 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 199.27.128.0/21;
real_ip_header CF-Connecting-IP;
    It's been happening on all of my servers. It seems like it does not return correct IP.

    Example: 108.162.219.104 appeared. I had to add this PHP code to get it to work:

    Code:
    if (isset($_SERVER["HTTP_CF_CONNECTING_IP"])) {
  $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
}
    Any reason why? maybe invalid IP Range..?

    Nginx 1.25.x
    MariaDB 10.x
    123.09beta01's tools/csfcf.sh works fine for me :)

    just be sure to uncomment include line in your vhost
    Code (Text):
      # uncomment cloudflare.conf include if using cloudflare for
  # server and/or vhost site
  include /usr/local/nginx/conf/cloudflare.conf;

    All that does, is commenting out the hash from cloudflare.conf then loading it? Wouldn't be much of a difference doing it manually :/ It only happened to specific users, for example someone from the US that was on Phone.

    Nginx 1.25.x
    MariaDB 10.x
    csfcsf.sh just automates the manual steps and if you setup cronjob regularly checks for new cloudflare ips to update your nginx and csf firewall whitelisting automatically

    have you contacted cloudflare tech support to see what the issue is for those specific users ?
