The Cloud Agent runs in the Cloud.

"Cloud" is a buzzword loosely meaning someone else's computer.

Their computer cannot access services running on your private loopback network interface (i.e. localhost).

If you want the Cloud Agent to access your service then you need to host it on the public Internet.
