SQL 2008 R2 Report Manager - The attempt to connect to the report server failed

Hi,

I am trying to get to the Report Manager page and get the following error message:

"The attempt to connect to the report server failed.  Check your connection
information and that the report server is a compatible version."

I am also unable to access the site using SQL Server Management Studio.  I am able to access Report Server (https://MyServer.com/ReportServer) without problem.

As suggested in the following article, I also tried from the reporting server with http://localhost/Reports and https://localhost/Reports without success.

The following is logged in the SSRS logfile:
