 Generally the error is happening, which means that your customer is not Can Connect Elast ICSearch Node (S). 
 
     
  •  Check that you are passing the right parameters for your customer 
    •  
  •  Check that you have no problem with the firewall 
    •  
  •  your status Provide a little more information, as Nick said, for example, do you deploy your elastic search on blue like auction cloud hospital? In this case your client may be out for example because he can not ping the nodes. 
    •  
 
 And you can also investigate some other similar cases here, e.g.
