daily cURL error 28 email but no error shown in logs

  • Every day around 6:00 am I get this email with an error notice from WP-Cron Status Checker:

    While trying to spawn a call to the WP-Cron system, the following error occurred:
    cURL error 28: Operation timed out after 3001 milliseconds with 0 bytes received

    When I check the plugin View Logs everything shows green. There is no indication of what the problem was. When I click to check now in the plugin, everything comes back green. Since my website is working fine, I tend to overlook this error message but it does worry me. Has anyone else had this problem, know what causes it, or know how to fix it?
