Unable to connect to remote server (SSRS)

I attempted to log into a new installation of SSRS Manager and received an error : Unable to connect to remote server .

This is what I did to fix the issue:

I went to C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\rsreportserver.config file.

I changed the value for the SecureConnectionLevel key to 0. It was previously set to 2.

<Add Key ="SecureConnectionLevel" Value="0"/>

I logged back into SSRS Manager and was able to after that.
