  <h2>So...</h2>
  
  <p>Firstly, I am on a company network and just a week back we published a fresh new app using Max OSX 10.9.3 (13D65) &amp; Xcode v5.1.1 (5B1008).</p>
  
  <p>This week, while trying to upload an update for this app via the same system, I ran into a few issues.</p>

  <h2>1st try<sup>*firewalled</sup></h2>

  <h2>2nd/3rd try<sup>*firewalled</sup></h2>
  
  <p>So, I got our network admin to open up port number 44001 and tried again.<br>
  Although it did reduce the number of errors, it failed again.

  Thought we'd try from another system but same error.</p>

  <h2>4th try<sup>*firewalled</sup></h2>
  
  <p>NOTE: No changes in network or system

  <h2>5th try<sup>*firewall bypassed</sup></h2>
  
  <p>So, I got our network admin to look into it and eventually we ended up bypassing the company firewall just for this upload session but it failed again.

  <h2>6th try<sup>*firewalled</sup></h2>
  
  <p>Thought we'd try from another system again so I switched to a colleague's system that hadn't been involved in this app's development, note that it was <strong>not</strong> bypassing the firewall, and it uploaded successfully in it's 1st attempt, albeit with a few warnings.</p>
  
  <ul>
  <li>System was a Mac OSX 10.9.3 that we later realized had an older version of Xcode (5.0) but anyways...</li>
  </ul>
