SpringCloud-Feign接口调用超时:feign.RetryableException: Connection timed out (Connection timed out) execut

刚开始代码里面使用的是：

@FeignClient("leak")
public interface LeakFeignServiceFeign {

在本地跑是正常的，上了测试环境，两个服务独立部署后，出现如下异常：

由于我这里是单机节点部署的，这里改成了使用IP进行调用，目前暂时这样改了

@FeignClient(value = "leak", url = "http://192.168.104.71:8888")
public interface LeakFeignServiceFeign {

重新部署，异常消失。
