title: Stuck on authenticating when uploading to App Store
body: <p>I've seen a few other SO questions that are related to this; but I've been through all of the fixes with no joy.</p>
  
  <p>My company had one Mac for use for the team. This worked absolutely fine. We really needed another so we have another. I exported the developer profile from the first Mac on to the second Mac. This <em>seemed</em> to work fine, we can test on local devices, etc. However, now we cannot upload on to the App Store from either Mac- they just get stuck on authentication with no error.</p>
  
  <p>Things I've done:</p>
  
  <ul>
  <li>Tried a different connection</li>
  <li>Set the HTTPS proxy port to 80</li>
  <li>Run the application loader and XCode at the same time</li>
  <li>Regenerate our certificates and provisioning profiles</li>
  <li>Set the build settings to various combinations of certificates and profiles</li>
  <li>Turn it off and on again (more than once)</li>
  <li>Update Java</li>
  <li>Bump version and build numbers</li>
  <li>Checked the licence agreement (no updates)</li>
  <li>Deleted the XCode DerivedData caches</li>
  </ul>
  
  <p>I can access the Apple developer sites just fine- developer.apple.com, the iTunes Connect stuff, all of that without trouble.</p>
