Hi Experts,
I tried to resolve the receiver system hostname in the URL and it is resolved in to 53.XXXXXXXXX.
We are working on an interface to POST the data to an receiver endpoint which is on internet.
I could successfully call the endpoint and get back the response using Postman tool as shown in below screenshot.

But, when I test the connection or try to make call from receiver HTTP channel of SAP Integration Suite(Cloud Integration) I get the following error.

When I do connectivity test from CPI tenant also it says host unreachable.

Thanks
Ramu
