title: jenkins keeps throwing Bad Message 431 reason: Request Header Fields Too Large
body: <p>I have recently upgraded to jenkins 2.89.4(jdk8). I am continuously getting below error on a redirected page whenever I go into the configuration tab of any jenkins job.</p>
  
  <pre><code>Bad Message 431
  
  reason: Request Header Fields Too Large
  </code></pre>
  
  <p>There is not enough help available on jenkins pages.
  The workaround I have is to go and remove the cookies but I see the same page again after 2-3 redirection.</p>
