Hi Siva,

Since the gateway and Remote IP is accessible from shell, it means the platform already has the valid gateway, then according the IP policy, it should be ready for the upper layer to access the Internet, UEFI HttpBootDxe driver has verified that by registering one valid gateway. So, the problem is quite possibly in your Http application. My suggestion is that you can check the source code and compare with the logic in the HttpBootDxe driver or you need share the source code to me if possible.

Thanks,
Jiaxin
