title: Nginx configuration catch uuid route
body: <p>I need to catch route in my nginx conf:
  <code>http://example.com/media/{uuid}</code><br>
  I'm trying:  </p>
  
  <pre><code>location ~ "/media/([a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12})" {
  // ...
  }
  </code></pre>
  
  <p>Uuid regexp is ok: <a href="https://regex101.com/r/bXMmFP/1" rel="nofollow noreferrer">https://regex101.com/r/bXMmFP/1</a>
  But it's not working on Nginx side. What I'm doing wrong?</p>
