Hi Guys,  
I am new to community. I configured the Licode server on ubuntu 16.04. I installed the demo app in a seperate VM running Ubuntu 16.04. When I try to start the demo app, I get the following error:  
demo@demo:~/licode-demos$ sudo npm start  
[sudo] password for demo:

> application-name@0.0.1 start /home/demo/licode-demos  
> node app.js

/home/demo/licode-demos/node\_modules/debug/src/node.js:132  
let val = process.env[key];  
^^^

This is my config.js file:  
ar config = {};

config.nuve\_host = ‘192.168.1.117’;  
config.service = {};  
config.service.id =‘531b26113e74ee30500001’;  
config.service.key = ‘mykey’;

config.demo\_host = ‘192.168.1.155’; // Without “http”, just the host.

config.http\_port = 80;  
config.https = false;  
config.https\_port = 443;  
config.ca\_certs = undefined;

[//config.plain](https://config.plain) = true;

module.exports = config;  
I randomly picked the service Id and key.

Please advise.

Thanks

I changed the nuve host entry in config.js file to [http://192.168.1.117:3001](http://192.168.1.117:3001) I got this error during the start of demo app:

> node app.js
