We were testing this out and got sidetracked for a bit due to other projects. Came back to it today and it says that the Probe Health is Down and Disconnected.
From the web UI I also get the message that "Monitoring may be incomplete or inaccurate due to fundamental problems in your PRTG instllation! Click here for more information!" When I click the link, I get the same information as above with no further details on how to fix the issue.
The last time data was collected was several weeks back. The first thing I did was to update to the latest version and that did not resolve the problem.
