Error occurred when i run the RemoteAttestation

Is there any network connection in this demo?

If there is one, i think it's a network problem, cause my machine needs proxy settings.

But i have no idea how to set proxy for sgx.

Start with the RemoteAttestation demo and reproduce the failure on a machine that requires a proxy. Trace whether the demo makes a network connection and identify the SGX proxy configuration path; done means the cause and supported proxy setup are confirmed or the issue is narrowed to a reproducible failure.
