For testing purpose same port 9073 added in IS without error that mean listening default port https @9073 not attached with API Gateway.
Server.log will upload, any other log need to capture please let me know.

I have set up the same environment in my system and drill down the issue, during investigation observed that the issue with the “Keystore file name” — To configuring the API Gateway User Interface for secure communication, accidently .jks extension missed out in Keystore file in \common\conf\ location.
