在服务器已经开放8848、9848、9849端口，并且服务也能成功注册到Nacos中，使用feign或者是gateway也能成功请求到服务接口，但是依然报错(After the server has opened ports 8848, 9848, and 9849, and the service can be successfully registered in Nacos, the service interface can also be successfully requested by using feign or gateway, but the error is still reported:)：

第一个： Server check fail, please check server localhost ,port 9848 is available , error ={}

网络代理也会引起这个问题，感觉是端口冲突了。关掉 clash 就好了。

我是这个问题,关了立马好了,离谱

同Nacos2.0.3 可以检查一下你的Maven打包配置 看下你打的包有没有缺失bootstrap.yml 我的是打包配置的问题
