Ops Manager 2012 Reporting Console in unavilable

Hi Everyone,

Health Explorer states:
The Reporting Console is unavailable. This was detected by pinging the reporting URL from the reporting server. By default, this monitor pings the reporting URL every 15 minutes.
Causes

This can happen if the web site hosting the reporting URL is not accessible or stopped.
Resolutions

Try the following troubleshooting steps to attempt to fix the problem:
Open your browser to confirm that the reporting URL is online.
 Ensure that the web site hosting the reporting URL is running

ReportConsoleWatcher Monitor
Microsoft.SystemCenter.WebInterfaceWatcherMonitoring: - WebSite http://server:80/ReportServer Failure on Server server Error Detail: Service Unavailable

However, given the above, I can generate Ops Manager 2012 Reports within issue from within the Console.

Environment:

Windows Server 2008 R2 SP1, SQL 2008 R2, Ops Mgr 2012 SP1 and SCCM 2012 (all on same machine)

Any ideas most appreciated!
