I made the diffrence you said and nginx restarted without fail. This is the 
final modified location/

        location / {

               proxy_pass http://127.0.0.1:8001;
               proxy_redirect          off;
               proxy_set_header        Host            $host;
               proxy_set_header        X-Real-IP       $remote_addr;
               proxy_set_header        X-Forwarded-For 
$proxy_add_x_forwarded_for;

               proxy_http_version 1.1;
               proxy_set_header Upgrade $http_upgrade;
               proxy_set_header Connection "upgrade";
        }

But unfortunately i get the same error on browser again as below :(

WebSocket connection to 'wss://localhost:8001/websocket/ask_service' 
failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED
