Failed to create channel by local ca for grpcs error

[favccxx]

I'm trying to generate certificate by java code, and I succeed to start orderer and peer, but I failed to create channel for grpcs error. I know there must something wrong with my tls certs. But i don't know the reason. Can you tell me the reason?

These client connection errors usually means that the client is not configured with a CA certificate that matches the signer of the server's TLS certificate.

I've opened a PR to add some more TLS troubleshooting information to the Fabric docs that may help you:
#3346
It is written from the perspective of a peer CLI client connection, but should be helpful for a Java SDK connection error as well.

What is the corresponding error in the peer log at the time of connection failure?
