We are using Packaged Integration: SuccessFactors Employee Central to ERP Employee Data Replication to send the data to a SAP HCM system which is on premise. The communication will happen via web-services. We have deployed the integration pack on Cloud Atom. Now my question is for successful usage of web-services which IPs of BOOMI/Cloud Atom should be whitelisted. The base URL under shared web-services reflects: https://boomi2.successfactors.eu. I have got 18.104.22.168 and 22.214.171.124 whitelisted at my 3rd party vendor end. But I am getting an error "Error invoking soap operation; Caused by: HTTP transport error: java.net.ConnectException: Connection refused; Caused by: Connection refused".
Kindly help me ASAP.
Thanks in advance.
