title: Did not observe any item or terminal signal within 60000ms, Java consumer side issue
body: <p>I have a cluster that has 2 java apps connected and it is trying to connect to the azure event hub but the below error is showing up.</p>
  <pre><code>2021-06-03 12:22:29,124 ERROR [com.tat.eve.ser.EventHubConsumerSercive] (parallel-1) NONE: java.util.concurrent.TimeoutException: Did not observe any item or terminal signal within 60000ms in 'flatMapMany' (and no fallback has been configured)
  </code></pre>
  <p>The app is not able to connect and hence cannot receive/publish the events to the event hub.
  Any help on how to resolve this issue?</p>
