Error in SOAP Receiver Adapter with HTTPS

Dear All,

I am developing a SOAP to SOAP scenario with HTTPS i.e. client without authentication and I am facing an issue with the receiver adapter. Few messages fails in the receiver side while rest are successful.

Error - Delivery of the message to the application using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: Failed to get the input stream from socket: iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier

Please let me know what can be the reason for the error.

Thanks and Regards,
