SOAP request over secure connection

Hi guys,

I'm trying to invoke a soap operation. I ran the configuration workflow adding the soap host (wsdl: https://xxx) and selected to import the certificate. At the vco control center I see the certificate at trusted ssl certificates, but when I ran some operation workflow I get the error: java.security.cert.CertificateException: Certificate is not in CA store.

Any ideas? what am I doing wrong?

thanks.
