rpcx 使用etcd作为注册中心，客户端无法连接failed to call: dial tcp [::1]:8972: connectex: No connection could be made because the target machine actively refused it.

[yongliangZhang]

rpcx 版本：v1.8.31 rpcx-etcd 版本：v0.4.0

客户端连接代码： `flag.Parse() d, _ := etcdclient.NewEtcdV3Discovery(basePath, "Arith", []string{etcdAddr}, true, nil) xclient := client.NewXClient("Arith", client.Failover, client.RoundRobin, d, client.DefaultOption) defer xclient.Close() args := &example.Args{ A: 10, B: 20, }

for {
    reply := &common.Reply{}
    err := xclient.Call(context.Background(), "Mul", args, reply)
    if err != nil {
        log.Printf("failed to call: %v\n", err)
        time.Sleep(5 * time.Second)
        continue
    }

    log.Printf("%d * %d = %d", args.A, args.B, reply.C)

    time.Sleep(5 * time.Second)
}`
