Running service occasional prompts “com.alibaba.nacos.shaded.io.grpc.StatusRuntimeException: UNAVAILABLE: io exception” #3597

网络波动问题？排查下 nacos 9848 端口看看 如果是容器部署的话，可以尝试把 9848 9849 8848 端口都放开看看（nacos 的端口偏移量是 1000 和 1001） 可以提供一个复现 demo，本地不好复现没办法验证问题 |
|
容器部署的，9848 9849 8848 端口都放开了，本地确实不好复现，这个异常是偶尔发生的，主要是看到了Caused by: java.io.IOException: Connection reset by peer这个提示，感觉是服务端或者客户端的某一方主动关闭了连接，怀疑是不是客户端和服务端的不匹配导致的呢？这两个版本是否存在兼容性问题？ |
nacos-client-2.1.2 nacos-server-2.1.0 不是很确定有没有兼容性问题，你可以参考 sca 的推荐的版本组件 可以试着从 spring-cloud-starter-alibaba-nacos-discovery中排除现有的 nacos-client 依赖，引入和 nacos-server 一致的看看 <dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
<exclusions>
<exclusion>
<groupId>com.alibaba.nacos</groupId>
<artifactId>nacos-client</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.alibaba.nacos</groupId>
<artifactId>nacos-client</artifactId>
<version>${nacos.client}</version>
</dependency> |

客户端与服务端通信中间是否有经过 Nginx 或其他代理转发 |
没有的，都是直接通过sdk连接的Nacos-server，本地又很难复现这个错误，但是部署到容器中就会偶尔有这个问题。 |

@chengyouling 本地可以用 Maven Helper 看看是否有依赖冲突，或者咨询一下 Nacos 社区之前是否有遇到过类似的情况。 |

nacos-client-2.1.0 |
主要依赖及版本：
spring-cloud-gateway-3.1.4
spring-cloud-starter-alibaba-nacos-discovery-2021.0.4
spring-cloud-starter-alibaba-nacos-config-2021.0.4
nacos-client-2.1.2
nacos-server-2.1.0
场景：gateway服务能正常启动，但是偶尔会有com.alibaba.nacos.shaded.io.grpc.StatusRuntimeException: UNAVAILABLE: io exception异常，8848、9848端口都是正常的
