title: Jenkins 2.192: HTTP Error 403: No valid crumb was included in the request
body: <p>I recently upgraded to Jenkins 2.192, and my applications started failing with the following error:</p>
  
  <pre><code>HTTP Error 403: No valid crumb was included in the request
  Reason: No valid crumb was included in the request
  </code></pre>
  
  <p>I do not see the problem after downgrading to Jenkins 2.189.
  I do not see the issue with Jenkins 2.189, 2.190, 2.191.
  I hit the issue with Jenkins 2.192 (also seen with 2.196)</p>
  
  <p>SOMETHING CHANGED BETWEEN 2.191 AND 2.192 , causing the failure I observed.</p>
