Ocelot网关：未知此类主机

Question

我使用Ocelot作为网关，使用Consul作为服务发现。在Ocelot.Errors.Middleware.ExceptionHandlerMiddleware [0]

中的第一个API调用Ocelot Gateway之后出现错误

我的输出日志在这里：

豹猫配置为：

{
  "ReRoutes": [
    {
      "DownstreamPathTemplate": "/{url}",
      "DownstreamScheme": "http",
      "ServiceName": "booking",
      "UpstreamPathTemplate": "/api/{url}",
      "UpstreamHttpMethod": [ "Get" ]
    }
  ],
  "GlobalConfiguration": {
    "ServiceDiscoveryProvider": {
      "Host": "localhost",
      "Port": 8500,
      "Type": "Consul"
    }
  }
}

在第一个电话中，一切正常，但是此后突然我遇到了错误。

我的问题在哪里？
