Thanks @sunnyajmera, for your response.
Here is the log -
Caused by: com.sap.conn.jco.JCoException: (102) JCO_ERROR_COMMUNICATION: Initialization of repository destination SAP HR [source] failed: Connect to SAP gateway failed
connection parameters: TYPE=A DESTINATION=“SAP HR [source]” ASHOST= SYSNR=00 PCS=1
Based on the error, I am assuming your SAP Instance is running on ASHOST value with 00 instance. Is that Port open, have you checked with system admins on firewall?
