I still have the question，eventhough project use the SpringBoot version：2.2.5.RELEASE，SpringCloud version：Spring Cloud Hoxton.SR3，SpringCloud Alibaba version：2.2.1.RELEASE（official recommendation）. How to solve it?

zj519718645 · 2021-03-03T10:09:38Z

这边使用的nacos-client 1.2.1依然存在这个问题。感觉是不是可以重试机制有点问题，另外连接超时时常是否可以适当调长一点。
