Im sorry, I know that there is a lots of topic regarding this problem.
But I dont really know what to do ?
I found in the support these below 2 points to resolve the problem:
I think that in my case the solution is in the point 2 (reverse-proxy) because I didnt find an A record pointing to Cloudflare IP ?
Thank you for your help…
1- If an A record within your Cloudflare DNS app points to a Cloudflare IP addressOpen external link, update the IP address to your origin web server IP address.
2 - There is a reverse-proxy at your origin that sends the request back through the Cloudflare proxy. Instead of using a reverse-proxy, contact your hosting provider or site administrator to configure an HTTP redirect at your origin.
