Unable to open connection to backend

508 Views

While sending PO from Ariba to SAP ERP following error is seen on CIG:

org.apache.cxf.transport.http.HTTPException: HTTP response '502: Bad Gateway. Unable to open connection to backend system' when communicating with https://ADDRESS_IS_SET_VIA.HEADER

Thanks in advance.
