Hello, i made an account on www.e-payouts.com , it’s a website for payments. they gave me a ip that you have to add to your white list. I put this ip from my account at whitelist, firewall, etc, but still not work.
They told me to talk to you, saying their IP is not accepted by you. The tell me: “Sometimes Cloudflare takes a few minutes to validate the ip. But if you want you can contact them to put our ip in white list. 137.74.17.102”
This does not seem to be an issue with the request being blocked, but rather that the IP address does not get rewritten, hence your PHP script never gets that address but only the one of Cloudflare’s proxy.
