title: HTTP 403 on images loaded from googleusercontent.com
body: <p>First off, I don't think my problem is related to these questions: <a href="https://stackoverflow.com/q/40570117/6319730">question 1</a>, or <a href="https://stackoverflow.com/q/29858287/6319730">question 2</a>.<br>
  Because I'm not using authentication anywhere, or any library either (I don't need to).</p>
  
  <p>I'm simply loading some publicly-available album art images in my web application:</p>
  
  <pre class="lang-html prettyprint-override"><code>// urlList is an array than contains URLs like the examples given below
  &lt;img *ngFor="let url of urlList" src="url"&gt;
  </code></pre>
  
  <p>Example URLs:
  <a href="https://lh3.googleusercontent.com/erjNVzk6nPUaUZuOTg2ObT12EzWWIokbuRdyuTkxRGR1nXQ5vhYk34twIt05FmaBNt7_yB3J" rel="noreferrer">Glass Mansion</a>, <a href="https://lh3.googleusercontent.com/3hAx--puGxM6w72CS-To0Ur1iAPru_u1Zwl7Ku_kQjkUXd25nWZTveou8c-aPe4ja631v8XLwlo" rel="noreferrer">Summertime</a>, <a href="https://lh3.googleusercontent.com/0R9lYLqpNtiVXrY7uJQe-1cY7jZHuPizUCXQme7XpFIIk7jv2ViusTnVPcZFOayX0TJObn8oBgc" rel="noreferrer">Side Effects</a></p>
  
  <p>99% of the time, it works. But sometimes I get 403 errors on the console for those exact same URLs.<br>
  I know they're not related to authentication, because, well. These URLs are publicly accessible.</p>
  
  <p>Debugging this has been difficult, because a few page refreshes later, it magically works again. There's nothing out of the ordinary in logs either (except the GET 403 errors).</p>
  
  <p>What in the world is happening?</p>
  
  <p>I'm using Angular v7.2.15. Browser: Google Chrome</p>
