title: Space Drain Failing to Restage with : Failed to fetch tokens from UAA
body: <p>I am deploying the space drain via the CLI and it works fine / as expected for about 10 days... and then when it attempts to restage itself when the refresh token expires I get these errors in the space drain log.</p>
  
  <pre><code>2019-08-09T19:32:18.897-07:00 [APP/PROC/WEB/0] [ERR] 2019/08/10 02:32:18 starting space drain...

  <p>Which appears to be directly related to this issue and the code sited /referenced in the issue in fact I can see the code generating the exact error.</p>

  <p>However I read through the issue but it was unclear to me what the fix is even though the issue is closed? </p>
  
  <p>If I try to restage it, it fails again the only way I get it to work is clean it up and re-deploy it with </p>
  
  <pre><code>cf drain-space syslog://&lt;sysloghost&gt;:&lt;port&gt; --drain-name my-space-drain
  </code></pre>
  
  <p>Then it works again until the token appears to expire ... repeat etc.</p>
