SP Could not query IAS and Client protocol error reading msg4

[liuxiaoxinxinxin]

Hi,
I'm trying to execute the run-server and run-client scripts for remote attestation.
But I'm getting the following error on the server side:

Waiting for msg3

Header contents:

HTTP/1.1 417 Expectation Failed

Date: Fri, 18 Nov 2022 08:59:10 GMT

Transfer-Encoding: chunked

Could not query IAS

attestation query returned 0:

Could not query IAS

Attestation failed

error processing msg3

Waiting for a client to connect...

and the following error on the client side:

protocol error reading msg4

How could I solve this problem?
Thanks,
Stefen
