title: What type of exception is a urllib3 connection failure?
body: <p>I have a section of code that gives me a urllib3 error when the IP address of the host it's connecting to is wrong, and also stops the App from starting up. </p>
  
  <p>This connection attempt is in a view(not the main view), which I'm assuming is being called when the application starts up.</p>
  
  <p>I want to write a <code>try</code> to check for this exception, however, the error doesn't mention what exception type it's seeing. </p>
  
  <p><strong>Q:</strong> What Exception type can I specify in the <code>try</code> to handle this error when then application starts up?</p>
  
  <p><strong>Error</strong></p>

  <p>Thanks in advance. </p>
