Purchase Code is not valid when I enter it local.

Hello,


I have recently purchased Fastkart template from codecanyon and installed it in my local.
While installing the Laravel backend, I have entered purchase code and envato username. But it says it is not valid.

This is the template that I purchased.
My envato name is Supermind.
Hope to solve this problem asap.
Thank you.

Your localhost settings may not be well configured to connect the author’s website to confirm the purchase. You can try to contact the item author and ask for support
