title: RefererNotAllowedMapError despite having referer specified in Key Restrictions
body: <p>I'm implementing the Maps JavaScript API onto a site, like I've done a thousand times, but this time, when I restrict the key to specific HTTP referers for the site and dev sites it'll appear on, it doesn't work.</p>
  
  <p>I've tried just about every permutation of the URLs, including with/without the protocol. I'm getting the <code>RefererNotAllowedMapError</code> error with a note "Your site URL to be authorized:" showing <em>the exact URL</em> that I've already added to the referers list.</p>
  
  <p>Variants I've tried thus far:</p>
  
  <ul>
  <li>mydevsite.com/</li>
  <li>mydevsite.com/*</li>
  <li>*.mydevsite.com/</li>
  <li><em>.mydevsite.com/</em></li>
  <li><a href="http://mydevsite.com/" rel="nofollow noreferrer">http://mydevsite.com/</a></li>
  <li><a href="http://mydevsite.com/" rel="nofollow noreferrer">http://mydevsite.com/</a>*</li>
  </ul>
  
  <p>None of my other sites have had this issue, but it's been several months since I needed to implement Maps on a site.</p>
  
  <p>Am I missing something?</p>
