访问不到网关服务，eureka上显示正常

Question

网关允许一段时间后出现如下日记就访问不了了
网关日记显示：com.netflix.discovery.shared.resolver.aws.ConfigClusterResolver - Resolving eureka endpoints via configuration
通过IP加端口可以访问服务，但是通过网关就不可以（返回 Could not get any response）
请问这是为什么呢？

1. 发出来的代码、日志，要格式化

2. 到底是不能访问网关还是不能访问服务

3. 都是在本机启动的吗

  不是本地启动，我有两个网关服务，运行一段时间后，其中一台直接返回502状态，另外一台也只有少量服务可以通过，重启也还是一样，但是等个几分钟又恢复正常

  502状态的那台服务，日记一直显示：
  com.netflix.discovery.shared.resolver.aws.ConfigClusterResolver - Resolving eureka endpoints via configuration

  你给的信息还是太少了。你就发了这一行的日志看不出来。下面发的都是info日志。现在的问题，是部分接口502是吗？那你可以调其中一个接口来排查问题。如果是经过网关之后才会出现502那你需要看一下接口的耗时，可能是网关请求服务超时了。
