The 'Flow Statistics' page doesn't show any data if accessing NFA with HTTPS/SSL.
For example: https://localhost/ra/Admin/FlowStatistics.aspx
1. On the NFA console backup the current the <Installed Drive>:\CA\NFA\REPORTER\NetQoS.ReporterAnalyzer.WebService\Web.config file.
2. Open the <Installed Drive>:\CA\NFA\REPORTER\NetQoS.ReporterAnalyzer.WebService\Web.config file with Notepad.
3. On line 174, change the security mode from "None" to "Transport".
For Example change from:
<security mode="None">
To:
<security mode="Transport">
4. Save the file and reload the Flow Statistics Page. There is no need to recycle any services or IIS.
