Unable to connect to Remote Server with SAP BC

After installing SAP BC and configuring the remote server settings, we are unable to connect to one of the servers, yet all other server connections work fine. Checked settings 3X over - so no issues there. Notice in the error log: iaik.security.ssl.SSLException: Untrusted Certificate, but the private/public keys are good to go and installed correctly. Any ideas where to look now?? Thanks!

I wonder if you trust the CA of the server you are connecting to.
