title: 'Clone URL is incorrect' when importing from GitHub to Azure DevOps
body: <p>I am trying to import a GitHub repository to Azure DevOps and I keep getting this error:</p>
  
  <pre><code>Import request cannot be processed due to one of the following reasons:
  
  Clone URL is incorrect.
  Clone URL requires authorization.
  </code></pre>
  
  <p>Here is a screenshot of my input parameters:

  <p>I have double and triple checked the cloning url and the authentication parameters. No matter what I put into the fields it always displays these two errors. 
  How can I trouble shoot this?</p>
