title: Connection Timeout for mongodb using mongoose
body: <p>I have a web application running on Node, express and MongoDB. I use mongoose as the ODM. When i tested my application with mongodb version v3.0.1 it runs fine and throws no errors. But when i run the same code v3.2.10 i get a connection timeout after some time.</p>
  
  <p>I get the following Error : </p>
  
  <pre><code>Error: connection timeout at null.&lt;anonymous&gt; (/webapp/node_module/mongoose/lib/drivers/node-mongodb-native/connection.js:186:17)
  </code></pre>
  
  <p>I use mongoose.connect for the db connection to the local mongodb instance.
  Has anything changed in the way of connection ?</p>
