Usign Nginx+https+cloudflare+ danea export

[Sanitaria]

Hi i just purchased some days ago the module to export product from my software to prestashop by using php, the problem is when i try to upload the file, it say this

 

On Cloudflare i disabled all https feature and stuff on that special url

"http://www.xxxxx.com/modules/daneaimport/gest.php?key=mypass

 

Also sometimes it fail to upload for "socket error"
