应用是.net core3.1 webapi ,Nacos sdk用的是1.2.1版本
系统运行一段时间就会报上边的警告信息，这时这个服务从nacos就请求不进来了

这个是触发了客户端和服务端的重连机制，做完全 redo 的操作后，服务是会重新注册和被发现的。

嗯，大概了解。那么grpc长连接 每5秒钟向nacos发送心跳，假设nacos服务一直正常。那么上边这个问题，有可能是grpcclient链接无法创建，或调用不可达的情况发生吗？

主要是什么情况下，能触发这个redo那。
而且redo之后，好像nacos重新注册，有段时间从nacos是调不进来服务的

@catcherwong @china9839 我的服务现在也会出现这个问题。突然间就断掉了。而且一直重连失败，要重启容器才行，不知道为什么。nacos-sdk包用的是1.3.5

[catcherwong]

@ROMYIM 有具体的日志吗？

@ROMYIM 有具体的日志吗？

我的问题和他类似用也是1.3.5，nacos版本2.1.1，连接成功后几秒就断了，我看是心跳检测不过，具体日志
