dubbo项目Connection refused (Connection refused)？

spring boot版本：2.4.2

spring cloud版本：2020.0.0

spring cloud alibaba版本：2021.1

java版本：1.8.0

本地环境：win10

测试环境：CentOS-8.2

首先 nacos 是肯定启动了且可以正常访问的。

服务提供者 和 服务消费者 模块在本地IDEA上直接运行没有这个报错，一切都是正常的，打成jar包以后在本地运行也是正常的，但我上传至Linux服务器之后运行 提供者 和 消费者 都会报这个错误。

但是！他们可以正常的注册到 nacos 并且可以正常的使用！和本地IDEA里直接运行没报错的没有任何区别！因为我jar包部署在虚拟机做测试，我也尝试了直接部署在阿里云上，也没用。我在网上也搜索了很多资料，唯一和我最接近的是官方github下Issues里的一位同志遇到的问题。

链接：https://github.com/apache/dubbo/issues/7059

里面提到了使用官方默认的日志框架就能解决，可我目前项目里也没添加其它的日志依赖啊。

Linux下的报错：
