Following automic upgrade to 12.3.8 was able to get the data updated analytics agent running and the pack loaded.
However trying to view a previously working dashboard it reports:
Cannot connect to the Analytics backend. Check the Analytics logs.
Release : 12.3.9
Component : ANALYTICS ON PREMISE
The Analytics backend is bundled into the IA Agent that is delivered with the Analytics package.
It connects to the Analytics datastore and to the Automation Engine database through the application.properties file,and to the Automation Engine through the ucxedda.ini file.
Confirm that the application.properties has both the correct api_key and backend endpoint set
In this use case after updating the ap ikey the issue was resolved and the dashboard was displaying correctly
