I'm using SAP ME 2.1 SP02. When I try to synchronise (using https instead of http in my settings), I get the following error on the server:
iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: certificate unknown
However I strictly followed what was described in the installation guide, especially the chapter 1.2 Enabling SSL on SAP J2EE Engine in the How-To Guide.
Can anyone help me?
