title: Android: error while installing v7 appcompat (app compat library)
body: <p>I cannot install app compat v7 library. I am following the instructions given at <a href="https://developer.android.com/tools/support-library/setup.html" rel="nofollow">https://developer.android.com/tools/support-library/setup.html</a></p>
  
  <p>Strangely,  instructions from above link used to work on my old system. I open SDK manager, select Android Support Library, accept licence and install. But I get the following error.</p>
  
  <p>Any suggestions appreciated (I spent several hours trying to figure this out)</p>
  
  <pre><code>       Downloading Android Support Library, revision 20
         Download interrupted: Connection to http://127.0.0.1:5050 refused
         Done. Nothing was installed.

  <p>I restarted the system. Turned off windows firewall (I donot have anti-virus). Started the SDKManager and tried installing. Again the same problem. Reviewing SDKManager log, I see following error messages (which came up when SDK Manager was started). I manually open all these error links on the web and I do see those files. However SDK Manager is not fetching them when it is first started and hence cannot install the app compat. Any idea on why SDKManager is able to fetch some files but not some other</p>
