user: p1 IP: ::ffff:127.0.0.1 URL in node js - node.js

Question

In my local setup of a node.js project I have a php page test.php. Now when in browser I put url http://localhost:8080/test.php I get the following error in console.
[12/28/2015 12:40:15] user: p1 IP: ::ffff:127.0.0.1 URL: /test.ph
Error requesting PHP backend (GET): Error: connect ECONNREFUSED.
Should I install some module of node js or it's a issue for my ubuntu version?
