title: Selenium grid is providing exception :PROXY_REREGISTRATION
body: <p>I am now able to run selenium grid 2 successfully, thanks to you guys. Now I am facing a new issue, i.e. : Session [xxxxx] was terminated due to PROXY_REREGISTRATION</p>
  
  <p>according to what i read it means that the node was disconnected and was retrying to connect to host, which failed.</p>
  
  <p>but what I want is, how to tackle this exception. rather how to handle it>>???
  Does anyone know something related to this one??</p>
