Problem: Upload content does not work in Google Chrome with Enterprise 10.7 and later on a Portal for ArcGIS machine


When uploading files to Portal for ArcGIS Content from your computer the "Add Item" button may not work with Google Chrome. The Add Item button remains unresponsive and no error messages are observed, including the developer tools. The issue is specifically observed on the Portal machine and prevents the users from uploading any type of content. The same content can be uploaded successfully using Internet Explorer and from other machines to the same Portal.


The issue occurs due to the Local Group Policy settings, which disables the user from uploading content to Portal for ArcGIS through Google Chrome. The Attachment Manager under the Windows component is responsible for this behavior.
