Page Not Found message when accessing Creative Cloud files from context menu

Adobe engineering is investigating an issue where selecting options to view local assets in a browser using context menus results in a "Page Not Found" message.  

Note: This issue only affects a limited number of customers.

Solution

The same commands available using the context menu locally are also available using a browser directly. Use the drop-down arrow below asset thumbnails to show the menu. Selecting menu commands through the browser doesn't cause the error.
