Connection problems

I am trying to use the local Blynk Server with my Raspberry Pi. I’ve been trying to run a piece of code on the Raspberry Pi and I get this error message:
OnOff mode Connecting to: xx.x.x.xx 8441 events.js:85 throw er; // Unhandled 'error' event ^ Error: connect EHOSTUNREACH at exports._errnoException (util.js:746:11) at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1010:19)

Here is my code:
var Blynk = require('blynk-library') var AUTH = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; var blynk = new Blynk.Blynk(AUTH, options= {addr:"xx.x.x.xx"});

What do I do?
