CDN's mystery, please explain by a big boss.

admin

The problem seems to be related to the use of Cloudflare CDN and its configuration. The issue might stem from an issue with the DNS records or caching mechanisms of the Cloudflare CDN. To resolve this, you can try disabling Cloudflare's caching mechanism for your domain by setting up a custom cache policy in the Cloudflare dashboard. Additionally, ensure that all necessary DNS records have been set up correctly and that the source IP address is not being cached on any of the nodes. It may also help if you check the Cloudflare logs for any errors or warnings related to your specific setup.
