sorry for the lack of useful information as i was replying via mobile.
1.) There’s some other processes running on port 8080 and the spark-server did not managed to fire up. If you are comfortable of looking up what is running on port 8080 and turn it off that would be great!
2.) You can change the port to something else for testing here: https://github.com/spark/spark-server/blob/650275feadaa5a5c28415df485ad3073e10b4e97/js/main.js#L97
But to make sure that your Spark-cli config file is updated as well
3.) The console log output that you should see if everything runs smoothly is:
Loading user ken@lc.com
connect.multipart() will be removed in connect 3.0
visit https://github.com/senchalabs/connect/wiki/Connect-3.0 for alternatives
connect.limit() will be removed in connect 3.0

Your server IP address is: 192.168.1.143
server started { host: 'localhost', port: 5683 }
the node app will run forever until you stop it or close the terminal
4.) Only 1 copy of the main.js needs to be running so there’s no need for an additional terminal etc…
