We have a website that was initially installed using HTTP and when it got to staging env a redirect was applied to use HTTPS, when this happened the display attached export link stopped working because it refers to the HTTP site URL. The issue is originated from what you can see in this picture:
But the views_data_export module forces the use of absolute URLs and that provokes HTTP over HTTPS requests which are blocked for browsers.
$url_options['absolute'] = TRUE;
$url_options['absolute'] = FALSE;
