Ошибка Grandnode: ресурс временно недоступен в System.Net.Dns.InternalGetHostByName (строка hostName)

Question

Добрый день.Я новичок в использовании Grandnode, и я попытался следовать инструкции по установке его с помощью Docker по этой ссылке: https://grandnode.com/weekly-tips-4-build-and-run-the-grandnode-with-docker-for-linux-containers. На последнем шаге, когда мне пришлось заполнить информацию и установить, я получил следующую ошибку:

 timeout occured after 30000ms selecting a server using CompositeServerSelector
{ 
  Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, 
  LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }. 
Client view of cluster state is

  ConnectionMode : "Automatic", 
  Type : "Unknown", 
  State : "Disconnected", 
  Servers : [

      EndPoint: "Unspecified/my-server:27017", 
      State: "Disconnected", 
      Type: "Unknown", 
      HeartbeatException: "MongoDB.Driver.MongoConnectionException: An exception occurred while opening a connection to the server. ---> System.Net.Internals.SocketExceptionFactory+ExtendedSocketException: Resource temporarily unavailable at System.Net.Dns.InternalGetHostByName(String hostName) at System.Net.Dns.ResolveCallback(Object context)

Кто-нибудь знает, как исправить эту ошибку?Большое спасибо за помощь!
