I would vote for removing OA, RPC and then install RPC and enable OA and try again

Start by verifying your certificate is installed and in the right place. You didn't say what the client OS is. If it is Vista or Win7, you can't let it automatically install the certificate. This includes using the certificate installer. It puts it in the wrong place. You need to install it in a trusted root certification authority and in a physical store - local computer by manually installing it.
