title: MassTransit Request Response sample
body: <p>I'm learning about MassTransit, so I downloaded the <a href="https://github.com/MassTransit/Sample-RequestResponse" rel="nofollow noreferrer">sample</a> they have however it doesn't seem to be working for me, I'm getting the following error when I try to start the service:</p>
  
  <pre><code>An exception occurred
  MassTransit.RabbitMqTransport.RabbitMqConnectionException: Connect failed: igor@localhost:5672/test ---&gt; RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---&gt; RabbitMQ.Client.Exceptions.OperationInterruptedException: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=530, text="NOT_ALLOWED - vhost test not found", classId=10, methodId=40, cause=
     at RabbitMQ.Client.Impl.SimpleBlockingRpcContinuation.GetReply(TimeSpan timeout)
  </code></pre>
  
  <p>When I try to use other examples using older versions of MassTransit they are working fine.</p>
