After the Authentication Method for Agents is changed to LOCAL_REMOTE (UC_AS_SETTINGS variable) it is not possible to download the Authentication Package via the CA Automic Web Interface in version 12.x onwards.
The issue is independent from the browser. It occurs with Chrome, Firefox and Internet Explorer/Edge.
After the click on Download Authentication Package nothing happens (no popup, no error message and no hint in the logfiles).
A bug that prevented the download of an agent authentication package has been fixed.
Update to a fix version listed below or a newer version if available.
Automic Web Interface (UI)
Automic Web Interface 12.2.0 - already available to download
Automic Web Interface 12.1.2 - already available to download
Automic Web Interface 12.0.5 - already available for download
Workaround for V12.0.x
use the JAVA GUI 12.0.2
