Error: unsupported protocol (remote attestation demo)

lemonviv commented 4 years ago

Hi Occlum-team,

I tried to run the remote attestation demo using docker, but got the following error:

aesm_service[14]: [ADMIN]EPID Provisioning successful
[ERROR][/root/demos/remote_attestation/lib/src/ra_ias.cpp:214] Fail to connect server: Unsupported protocol
Fail to get quote or fetch report, erro code is 5020000!

It seems to be a problem caused by the curl_easy_perform command when contacting with IAS, where the https protocol is not supported. But the installed curl indeed supports it.

root@100f32bc78de:~/demos/remote_attestation# curl-config --protocols

I wonder is there any configuration that is overlooked in the provided bash files? Any suggestions would be highly appreciated.

Thank you, Yuncheng

We do find the same issue in the current version Occlum. Will fix it soon, maybe this week.
