title: SSLHandshakeException when trying to reach app engine endpoint
body: <p>I'm trying to connect to one of my endpoint methods from an android client to my locally running app engine backend. The problem is I'm getting a SSLHandshakeException. My API is not protected by OAuth. The method I am trying to reach looks like this:</p>
  
  <pre><code>@ApiMethod(name = "register")
  public UserInfo registerUser(UserInfo userInfo) {
      try {
          checkUserParameters(userInfo);
          ofy().save().entity(userInfo).now();
          return ofy().load().entity(userInfo).now();
      } catch (InvalidPropertiesFormatException e) {
          logger.info(e.getMessage());
          return null;
      }
  }
  </code></pre>
  
  <p>And from my client I am doing this: </p>
  
  <pre><code>  if (regService == null) {
              UserInfoApi.Builder builder = new UserInfoApi.Builder(AndroidHttp.newCompatibleTransport(),
                     new AndroidJsonFactory(), null)
                  .setRootUrl(LoginActivity.LOCALHOST_IP)
                  .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
                      @Override
                      public void initialize(AbstractGoogleClientRequest&lt;?&gt; abstractGoogleClientRequest)
                              throws IOException {
                          abstractGoogleClientRequest.setDisableGZipContent(true);
                      }
             });
  
             regService = builder.build();
             UserInfo userInfo = new UserInfo();
             userInfo.setGcmId(registerToGcm());
             userInfo.setAccountName(params[0]);
             userInfo.setEmail(params[0]);
             userInfo.setProfilePictureUrl(null);
             UserInfo userInfo = regService.register(userInfo).execute();
    }
  </code></pre>
  
  <p>For some reason this does not work, I have also tried with the API that you get when importing the backend module to android studio but it gives the same error. </p>
