在构建docker容器之前，我正在本地处理Webhook，并希望我的（Linux）容器使用host.docker.internal:ping与之通信。
它以前一直在工作，但是最近，由于某种原因，我从我们的graphql-engine Hasura那里得到了这个错误：

    { 
   "timestamp":"2019-11-05T18:45:32.860+0000","level":"error","type":"webhook-log","detail":{ 
      "response":null,"url":"http://host.docker.internal:3000/simple/webhook","method":"GET","http_error":{ 
         "type":"http_exception","message":"ConnectionFailure Network.Socket.getaddrInfo (called with preferred socket type/protocol: AddrInfo {addrflags = [AI_ADDRCONFIG],addrFamily = AF_UNSPEC,addrSocketType = Stream,addrProtocol = 0,addrAddress = <assumed to be undefined>,addrCanonName = <assumed to be undefined>},host name: Just \"host.docker.internal\",service name: Just \"3000\"): does not exist (Temporary failure in name resolution)"
      },"status_code":null
   }
}   

这是我的码头工人组成：

本地项目肯定可以正常工作，并且正在侦听端口3000。但是，它没有从graphql-engine容器接收任何请求（应有）。可能与我们的代理有关吗？
