Ping failed while setting an OData connection for IGW service in Agentry Editor

Hello Experts,

I am trying to establish an OData connection in the Agentry Editor for the service which has been exposed via Integration Gateway but seems its not working.

I am able to access same URI in a browser with same credentials.

Both SMP 3.0.5 server and Eclipse are on the same machine. There is no firewall involved.

I am able to see a success message if i try with publicly available service, https://sapes1.sapdevcenter.com/sap/opu/odata/IWFND/RMTSAMPLEFLIGHT/

What could be the reason? Any clues?

Regards,

JK
