ue-ra EPID Provisioning issue

I tried to run the ue-ra both server and client on the same machine. When I try run ue-ra-client after run ue-ra-server it showed like this.
`Starting ue-ra-client
Connecting to localhost:3443
new client from 127.0.0.1:55226

I followed the precess of "[Custom CA/client setup](https://github.com/apache/incubator-teaclave-sgx-sdk/issues/new#custom-caclient-setup)", could any one help me to find out anything is wrong?

Start by reproducing the ue-ra server/client run on one machine using the linked Custom CA/client setup. Examine the EPID Provisioning protocol error, SGX_ERROR_UNRECOGNIZED_PLATFORM, and the panic at src/main.rs:95:29. Done means identifying the provisioning or platform failure and confirming that the client completes without the connection reset.
