Summary

To assist Cloudflares in resolving the cache-origin mismatch, support staff must retrieve specific logs from your web server. These errors are often related to stale cache responses versus the original request data. The issue stems when the origin server sends invalid or incorrect content to the cached resource.

If this error persists, you should investigate the provided logs to verify the discrepancy between the cache data and the server response. Detailed debugging may reveal timing issues or protocol failures causing the discrepancy.
