一、该问题的重现步骤是什么？

1. 通过 postman 调用 feign提供者能正常访问

2. 通过程序调用 feign 报错

二、你期待的结果是什么？实际看到的又是什么？

期待正常返回数据

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

bladex2.8.1 centos8

四、请提供详细的错误堆栈信息，这很重要。

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'retryableRibbonLoadBalancingHttpClient' defined in org.springframework.cloud.netflix.ribbon.apache.HttpClientRibbonConfiguration: Unsatisfied dependency expressed through method 'retryableRibbonLoadBalancingHttpClient' parameter 2; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ribbonLoadBalancer' defined in org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.loadbalancer.ILoadBalancer]: Factory method 'ribbonLoadBalancer' threw exception; nested exception is java.lang.IllegalStateException: Can not get service instances from nacos, serviceId=null

五、若有更多详细信息，请在下面提供。

说是 serverName 找不到，配置了 spring.cloud.nacos.discovery.service 还是调用feign 报错

你是所有的feign调用都报错还是只有你写的这个报错？如果所有都报错那就是工程本身没有依赖完整，如果只有自己写的报错需要把你的代码贴出来，否则无法判断
