title: While connecting two app servers with an ibm http webserver, we are able to successfully connect with only one server
body: <p>While running two app servers (which has mobilefirst servers hosted 7.1 version) from ibm http server, only one server runs successfully on keeping only one of the Route attribute active in the plugin-cfg.xml of the http server. In the server which is not running, the following error is seen in the messages.log. </p>
  
  <p>CWWKS4001E: The security token cannot be validated. This can be for the following reasons
  1. The security token was generated on another server using different keys.
  2. The token configuration or the security keys of the token service which created the token has been changed.
  3. The token service which created the token is no longer available.</p>
  
  <p>Kindly guide in resolving the error above. 
  Thanks. </p>
