title: Jenkins not able to use SVN credentials or download new plugins/new versions
body: <p><strong>Can anyone suggest how to fix the two issues?</strong></p>
  
  <p><strong>- Can't upgrade Jenkins and SVN plugin</strong></p>
  
  <p><strong>- Can't connect to svn</strong></p>
  
  <p>I am setting up Jenkins on a Windows 64 bit machine.  It's configured to run as a windows service.</p>
  
  <p>We are running this on Windows 7 64 bit OS</p>
  
  <p>Jenkins 1.482</p>
  
  <p>I am able to do an SVN update/checkout from my user account on the machine.</p>
  
  <p>When I attempt to set up a job on jenkins I get the following when trying to add svn credentials</p>
  
  <pre><code>FAILED: org.tmatesoft.svn.core.SVNErrorMessage: svn: OPTIONS /svn/client/trunk failed
  </code></pre>
  
  <p>More details are:</p>
  
  <pre><code>FAILED: org.tmatesoft.svn.core.SVNErrorMessage: svn: OPTIONS /svn/client/trunk failed
  
  org.tmatesoft.svn.core.SVNException: svn: OPTIONS /svn/client/trunk failed

  <p>I stopped the service and ran Jenkins from command line and tried the same thing - with the same result.</p>
  
  <p>I am able to connect to the svn server with a tortoise client and via firefox with the same credentials.</p>
  
  <p>In researching the issue I saw a few posts about similar problems and the only one that seems to claim to fix it is rolling back to Jenkins svn plugin version.  </p>
  
  <p>I then tried to install the latest jenkins and Plugin for svn.  The downloads failed.  Aha, I thought - obviously a firewall issue.  So I disable the firewall.</p>
  
  <p>Still no good.  I can't automatically download or get the new Jenkins or SVN plugin.</p>
