kratos: [Question] context deadline exceeded

version: github.com/go-kratos/kratos/v2 v2.0.0-rc6

按教程配置kratos，并使用etcd注册发现服务。 registry.Discovery的GetService是可以获取得到服务的Endpoints信息。

conn, err := grpc.DialInsecure(
		context.Background(),
		grpc.WithEndpoint("discovery:///servicename"),
		grpc.WithDiscovery(r),
	)
	if err != nil {
		panic(err)
	}

	cli := ccv1.NewConnectorClient(conn)
	reply, err := cli.CreateConnect(context.Background(), &ccv1.CreateConnectRequest{
		Username: "root",
		Password: "root",
	})
	if err != nil {
		log.Fatal(err)
	}

但是这样会报错： rpc error: code = DeadlineExceeded desc = context deadline exceeded

这可能是什么原因造成？
