title: Unable to add custom Domain w/ Google App Engine
body: <p>I'm unable to map a custom domain to my Google App Engine app. The steps I've already taken are:</p>
  
  <ol>
  <li>I'm the admin of the Google Apps account</li>
  <li>I'm the owner of the Google App Engine Account</li>
  <li>I've added the domain to the "Domains" section of Google Apps</li>
  <li>I've verified ownership of the domain within Google Apps</li>
  <li>I've correctly setup the MX records of the domain</li>
  <li>I've checked that the domain was correctly setup using: <a href="https://toolbox.googleapps.com/apps/checkmx/">https://toolbox.googleapps.com/apps/checkmx/</a></li>
  </ol>
  
  <p>However, for the last 3 days in the Domains section of Google Apps it says "MX records setup validation in progress".</p>
  
  <p>Additionally, when I go to add the domain within the Application settings of the Google App Engine account I get redirected to a sign in page (despite already being signed in, and an admin within Google Apps, and the owner of the Google App Engine app). Either way when I go to sign in again I just get redirected back to the signin page and I'm not able to get any farther.</p>
  
  <p>Also, I have billing enabled for the App Engine account. I've configured app engine domains numerous times before and never had these issues. Any help would be appreciated.</p>
  
  <p><strong>Update:</strong></p>
  
  <p>Following @presveva's suggestion I setup a new Google Apps account (despite already having an existing one) and the first page after creating a new Google App was a server error. After refreshing the page and verifying ownership of the domain I went to add the domain to App Engine. </p>
  
  <p>On the "Please accept the Google App Engine terms and conditions to continue" page, first of all no terms even showed (numerous XMLHttpRequest errors on the page), and after submitting "I accept. Continue to add this service" the next page stated "An error occurred while trying to install this application. Please try again later." </p>
  
  <p>This process is horribly broke and would be great if Google addressed this.</p>
