Cerficiate Error with FTPs connection

I am experiencing the aproblem with anFTPS connection. We already have two vendors using FTPS successfully. I have loaded the certificate into NWA Java Keystore (We are 7.11 EHP1 SP6). When attempting to send a document to the FTP server I get the following message.

Error when getting an FTP connection from connection pool: com.sap.aii.af.lib.util.concurrent.ResourcePoolException: Unable to create new pooled resource: iaik.security.ssl.SSLException: Error decoding Certificate: java.security.cert.CertificateException: Certificate format error: java.lang.ClassCastException: class java.lang.Integer:null incompatible with class [B:null

FYI - We are able to communicate using FTP and I am able to connect to the client from home via FTPS. So I can confirm the FTP server is operational, it will work via FTPS and IP addresses aren't being blocked.

Any suggestions would be appreciated.

    Hi Robert,

    Have you had some problem or warning in certificate uploading phase (in NWA)?

    You can refer to this 3D (is in XI 3.0, but in PI is simply the same procedure):
