Description

Environment

Dubbo version: 2.7.8
Operating System version: Windows10
Java version: 1.8
Spring-cloud-alibaba：2.2.6.RC1
duboo + Nacos

Steps to reproduce this issue

架构：3个服务，demo-account-service，demo-order-service，demo-gateway-api

demo-gateway-api 调用 demo-order-service，demo-order-service 调用 demo-account-service

先后启动 demo-account-service，demo-order-service 正常启动 demo-gateway-api 的时候就报异常，好像是元数据服务不存在，在nacos控制台中已经存在注册的服务了

Expected Result

正常调用服务

Actual Result

What actually happens?
