error displaying instagram feed using sp page builder joomla addon

I’m trying to display my instagram gallery feed on my website using the sp page builder add-on.
I enter the “Facebook App ID” and the “Facebook App Secret” and click on “Generate Access Token” and the facebook screen opens blank. On the site that is on localhost it works, but on the site that is on the server it doesn’t.
Website in Joomla 3.10.9
