Hello There, As my provided solutions not working, we have to Troubleshoot and find out why this not working, maybe we need to check the server time zone. Or we can set a corn job with 30 min or less and have to check whether it’s working or not. With my server, it’s working fine let me check by myself why it’s not working and fix the issue.

From My Side: First, I’ll check Our Plugin version (WP Rocket), and if an update needs I’ll do that. I’ll recheck the configuration of the plugin. After that, I’ll check the corn configuration. Make sure the file path is right and working fine. Without the invalid file path or misconfiguration that should work.

Thanks
