[GitHub] [dubbo] mz0113 opened a new issue, #10336: 3.0.5 应用级注册：消费端刷新服务列表获取元数据信息时因网络不通导致所有服务不可用

3.0.5版本的
前提：
某接口服务提供者有2台，分别为A和B，采用应用级方式注册到同一个nacos上，消费方启动后需要调该接口。
提供者A和消费端是跨网段的不互通，B和消费者是互通的。
错误表现：
消费方日志启动后就在刷refresh 什么meta failed，can`t get meta from xxx之类的错误，消费端调用时显示 all valid invokers size = 0，也就是说消费端现在一个可用provider都没拿到，手动去nacos上把服务A下线掉，稍后调用就正常了，可以调用到B上。
我的理解：
猜测是获取元数据信息是在一个for循环里面？导致其中一个provider无法联通报错导致for循环被break掉了，后续的provider也无法正常获取元数据了？

可以升级 3.0.9 版本看下，最新版的逻辑已经改成随机选一台了，如果有查询失败的过一段时间后会自动重试，会再次重新选择一台。
