Before asking for your help, I still tried to find the solution.
• Before, my comments worked. I do not know when it happened. So I can not even know where the problem is.
• I use Cerber. But nothing indicates comment settings to block them.
• I use the DIVI theme. I put the Safe Mode (disabling all extensions) and despite that, nothing works. I also changed the theme and it does not come from the theme either.
• I replaced the wp-comments-post file. php in case he was damaged.
So, I guess the problem is coming from Cloudflare because plugins and themes aren’t guilty !
I guess I did a right configure on Cloudflare but maybe I miss something ?
I deactivate all my plugins to try and replace with another theme. (Twenty-One)
Nothing works.
As seen, it is generate a IP adress when you comment an article. So maybe the problem is about Cloudflare because it is the only tool which have access to the IP and redirecting.
Lots of people, including myself, use WordPress on Cloudflare, so I know it’s possible to for Comments to work.
It looks like you’re minifying code. If you put Cloudflare into Development Mode for your domain, do you still get the error?
I also find it odd that the error includes the IP address of the Cloudflare proxy. That indicates that your web server is not restoring visitor’s IP address. Not that this is the cause of the problem, but it doesn’t help.

Yes, I think WordPress and Cloudflare could work together. Cloudflare manage the files and the problem about URL. The problem is from Cloudflare I guess. I open a ticket on WordPress and they think the problem is Cloudflare.

Yes, I minify code with Autoptimize and with Divi. I hadn’t a problem. I did pu Cloudflare into Development Mode and the error still here.
