[FIM Reporting] Start-FIMReportingIncrementalSync.ps1 fails

I am deploying FIM 2010 R2 SP1 Reporting on a test environment. However, in the post installation phase, the Start-FIMReportingIncrementalSync.ps1 script is failing with the following error (the Start-FIMReportingInitialSync completed successfully though). Any insight on what's causing this and how to resolve it?

Import-FIMConfig : Failure when making web service call.
