In SharePoint 2013 it was possible to post data (files) to /_layouts/15/upload.aspx?IsAjax=1&List={GUID}&RootFolder=/Sites/Site-A/LibraryName as a means to uploading files to a library.
Why is it not working anymore?

    Hi @Fernando Vargas ,
    According to my testing, please try to change the "IsAjax=1" as "IsAjax=2",it can upload files.

    Here is an example you can refer to:

        /_layouts/15/Upload.aspx?IsAjax=2&List={GUID}&RootFolder=/sites/site/Library-Name
