Encounter errors unless running the client using sudo

[yanzifan021]

Hi,
compiled with lastes bazel 3.2

If i run the client without sudo, i will encounter the follow error:

Client: Generating keys...
Client: Starting the protocol.
Client: Waiting for response and encrypted set from the server...
Client::ExecuteProtocol: failed to StartProtocol: 13: GrpcClientMessageSink: Failed to sen          d message, error code: 14, error_message: failed to connect to all addresses

However, running with sudo solve the issue.
Do you have any idea to fix this?
Thank you!
