<img width="899" alt="image" src="https://user-images.githubusercontent.com/15642586/212581714-d139462d-86fd-411d-9c3b-8d24ca49527c.png">
有时候A服务调用C服务时报错没有服务提供者，但是B服务调用C服务正常。且注册中心Nacos中A/B/C服务都有提供注册，且A/B是C服务的订阅者。一切看上去都正常，但A调用C就是会报错没有服务提供者，重启C服务就恢复了。
Dubbo版本 3.1.2
Nacos版本 2.1.2

有的 就是C服务发布重启 偶尔会出现A服务调用C服务找不到提供者 但是这个问题必须要等C服务下一次再次重启才能解决

你好，可以咨询下具体升级的版本号吗。目前我还是有这个问题
这是我的配置
Dubbo版本 3.2.4
Nacos服务版本 2.2.3
<nacos-discovery-spring-boot.version>0.2.10</nacos-discovery-spring-boot.version>
<nacos-client.version>2.1.0-BETA</nacos-client.version>

> 具体这个 [43c4033](https://github.com/apache/dubbo/commit/43c4033e11c07a59cb052a4ee7a18b95b26de707) NacosAggregateListener 的原理，网上搜不到介绍， @AlbumenJ 方便简单介绍一下么？ 修复了什么场景下的bug呢
由于 2.6 Nacos 订阅格式的历史问题，老版本的订阅格式上如果 group 或者 version 为空会忽略多余的 `:` 配置，导致如果一个服务 group 为 `xxx` version 为空，另外一个服务 group 为空 version 为 `xxx` 会被识别为同一个服务。因此在 2.7.4 版本切换到了新的订阅格式，无论 group 或者 version 有没有值都会拼接 `:`。
而 3.1.6 版本以前的 Nacos 订阅存在推送覆盖的问题，通常情况下只有新的 2.7.4 以后版本的格式有数据，但是在一些特殊情况下 Nacos 会对 2.6 Nacos 订阅格式的监听也进行空推送，导致覆盖了本地的地址列表，进而出现 No Provider。
这个 case 其实修了好几次，等到 3.1.6 才最终彻底修复，我们也欢迎有兴趣研究这个问题的同学撰写相关的文章～

您好，关于您在第二点提到的nacos可能存在推送丢失问题，方便看下我的这个case是否可能是这个原因导致的呢？就是nacos把provider的ip推给dubbo了，但是这个推送丢失了。

A 的 Dubbo 日志有都输出吗，可以贴下相关的日志吗

使用k8s 容器，内部启动docker服务， 生产者重启后ip变成新的了， 但是消费者还是使用旧的生产者ip连接，造成找不到生产者。

猜测是开启了推空保护引起的，可尝试关闭推空保护，具体查看[文档](https://www.bookstack.cn/read/dubbo-3.1-zh/4a2641af52b3c42f.md#5.%20%E9%BB%98%E8%AE%A4%E5%85%B3%E9%97%AD%E6%8E%A8%E7%A9%BA%E4%BF%9D%E6%8A%A4)

1. No provider 是一个综合性的问题，服务端没有正常启动，注册中心推送有没有延迟，消费端是否建连成功等都会影响

同样出现这个问题，环境：k8s、nacos server 2.1.0、nacos client 2.1.0、jdk11，dubbo 3.0.4。
a、b consumer、c provider 三个服务，都运行的好好的没重启。b服务每次都是启动正常调用c，过一会就会报错。
`No provider available from registry nacos:8848 for service com.***:1.0.0 on consumer xxx.xxx.xxx use dubbo version 3.0.4, please check status of providers(disabled, not registered or in blacklist).
org.apache.dubbo.rpc.RpcException: No provider available from registry nacos:8848 for service com.***:1.0.0 on consumer xxx.xxx.xxx use dubbo version 3.0.4, please check status of providers(disabled, not registered or in blacklist).`
