I recently just installed Matomo, and I noticed that all IP addresses that are logged are using cloudflare’s IP addresses. And yes, I already enabled the correct proxy headers according to:
https://matomo.org/faq/how-to-install/faq_98/
I even have a list of all cloudflare IP’s set up in a config file:

Just a small note. This does work on Xenforo, all IP’s shown there are real IP’s. I even created a simple php script to return my IP address (on a cloudflare DNS enabled domain) and it returns my own IP just fine.
So, what’s going on? Why isn’t it working? The config file itself appears to work, as I also added an SSL force which worked just fine.
