title: sbt does not resolve Typesafe repository
body: <p>I have an odd problem with sbt and the Typesafe repository:</p>

  </code></pre>
  
  <p>I can manually download both .pom and .jar from <a href="http://repo.typesafe.com/typesafe/releases/com/typesafe/play/play-json_2.10/2.2.0/" rel="noreferrer">http://repo.typesafe.com/typesafe/releases/com/typesafe/play/play-json_2.10/2.2.0/</a> so the server is definitely there.</p>
  
  <p>Is this perhaps an sbt problem? Any clues why it would fail if it definitely has the right URL?</p>
