got CRL expiration error when launching client

[wangsu502]

Hi,
I was trying to launch onnx client, and got the following error.
it's in ubuntu 18.04 and I've installed sgx sdk 2.11 and dcap driver 1.8
Anything else I need install?
thanks,
Leo

Sounds like you're not running this on Azure. At the moment we don't provide support/instructions for this scenario. If you figure it out feel free to submit a PR :) It's probably related to using the Azure DCAP Client in the server image vs. the Intel variant on the client host.

Check that the error is solved with az-dcap-client (and your clock is set correctly). The underlying problem is likely that the Azure cache is lagging about one month behind Intel. You can try building the server to use the Intel DCAP following the instructions at https://github.com/openenclave/openenclave/blob/master/docs/GettingStartedDocs/Contributors/NonAccMachineSGXLinuxGettingStarted.md
