  <pre><code> [DeploymentService:290066]Error occurred while downloading files from Administration Server for
   deployment request "62,790,652,848,356". Underlying error is: "null"
  </code></pre>
  
  <p>I have taken the following action to solve this problem.</p>
  
  <p><strong>1) stoped both admin and managed server and start those.(The admin server is sucessfully started but the Managed server is generating the above error and started in admin mode.</strong></p>
  
  <p><strong>2) took backup of tmp folder and deleted old tmp folder and restarted both admin and managed server , then also I am getting the same error.</strong></p>
  
  <p>I need your support to resolve this problem as I am able to access the site , which is on production.</p>
  
  <p>The same sever was working before but today when I tried to deployed the web app changes which was a small change(Included a coulmn in my jsp file) .The managed server is started generating this error. Now even if I rollback the changes and try to deploy this , it is still generating the same error<a href="https://i.stack.imgur.com/9cP5Z.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9cP5Z.png" alt="enter image description here"></a></p>
