2797823 - Certificate related error in PI SOAP Lookup channel

Symptom

  • In a Process Orchestration (PO) or Process Integration (PI) scenario which uses a SOAP Lookup receiver channel you get the error below:
    SOAP: Call failed: java.io.IOException: Communication over HTTPS. Unable to create a socket error.
  • This is an intermittent error and the majority of messages are successfully processed by this interface.
  • On checking the traces (XPI Inspector and/or defaultTrace) you can see the more detailed error: 

    Error while calling the SystemAccessorHMI's process Exception during processing the payload. Error when calling an adapter by using the communication channel <channel name> (Party: , Service: <service name>, Object ID: 425410f0g737391arrf16ef331d7867e) XI AF API call failed. Module exception: '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'. Cause Exception: 'java.io.IOException: Failed to get the input stream from socket: iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier'.

  • On checking the certificates used in this interface (via the XPI Inspector tool or directly in the Keystore), everything appears to be correct - besides most messages get successfully processed.
