Web based images doesn't load using vartiables in illustrator

Hello, using variables panes I used to be able to load web hosted images into a data set, unfortunatetly this images aren´t loading anymore, I got a real trouble because i can`t load the images from the link contained in the csv (The links were cheked and they work rigth), I tried to do it but nothing happens, I did an experiment relocating some of the images in a local folder and it worked, anyone knows what elese I have to check, any tip will be usueful, because I'm stuck in the midle of the work and it's starting to be an emergency.
