2551819 - UntrustedURLConnectionIOException: RequireClientCertificate is set, but no local certificates were negotiated.


You are sending a SOAP request message using a SOAP receiver channel in your IFlow to the target webservice. The target service requires client certificate authentication, therefore you set the correct Private Key Alias in the receiver SOAP channel. But the message processing fails with this error:

org.apache.cxf.interceptor.Fault: Could not send Message., cause: org.apache.cxf.transport.http.UntrustedURLConnectionIOException: RequireClientCertificate is set, but no local certificates were negotiated. Is the server set to ask for client authorization?
