Now I noticed that my php site incorrectly determines my IP ($_SERVER [‘REMOTE_ADDR’]). I am using nginx, which is configured according to the instructions Restoring original visitor IPs – Cloudflare Help Center . There is definitely no error in the configuration - everything worked before, the current lists of IPv4 and IPv6 addresses are taken from here https://www.cloudflare.com/ips/ . The scripts use a check for the user’s IP address and today I noticed that the check does not work. I started to understand and realized that my address for Cloudflare is defined as 193.233. x. x, which is actually not true.
Can you tell me what could have happened?
