Importing demo data Error

Hi,
I installed the Airi Pro plugin and Atived it by a license key; I want to import Demo data by One Click Demo Import; but but got the below error: “An error occurred while fetching file from: https://athemes.com/wp-content/uploads/demo-content/airi/airi-dc-business.xml !
Reason: http_request_failed - cURL error 28: Connection timed out after 10001 milliseconds.”
Can you help me to Fix it?
Thanks

Hello there,

This kind of issue is usually caused by server miss-configuration that can’t complete a task given from WP site’s admin. Please consult to your web hosting support department. Memory limit probably need to be increased. For additional information, please read this article https://www.samuelaguilera.com/post/curl-error-28-wordpress
