Issue:
There is an issue with scan nodes not being able to connect to F-Secure back-end servers. In short, the Last seen and Engine update indicators on https://portal.radar.f-secure.com/mmc/settings/scannodes.aspx show a delay of more than 3-4 minutes.
Resolution:
To troubleshoot the scan node connectivity:
1. Make sure that the F-Secure Radar Scan Node Agent (legacy name= Karhu.Scan.Daemon) service is running. Check this by using Windows Task Manager or Windows Local Service.
