Export to PDF is not working

Export to PDF feature is NOT working as https://export.dhtmlx.com/gantt is NOT loading. I am getting error as “Mixed Content: The page at ‘’ was loaded over HTTPS, but requested an insecure script ‘http://export.dhtmlx.com/gantt/api.js’. This request has been blocked; the content must be served over HTTPS.”

Please let us know how to make it working.
