That’s good you have backup - very important.

You shouldn’t need to install anything - except if you use non-standard Node modules.

Is it your own code or is it a project you have downloaded? If it’s your own code, then you need to post it in www.pastebin.com so we can have a look at the configuration, because it seems like it’s not configured correctly. If it’s a project, which and from where have you downloaded it?

just power off the droplet by sudo poweroff and then switch the power on using control panel.

@k0ala

Okay, those configurations doesn’t seem to do anything and it doesn’t match the ports the services are listening on.

So you’re only interested in running a Node.js application ?

May I recommend that you start over by reinstalling the server, following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-16-04

Otherwise you could start a droplet using the One-Click App, which would give you a pre-installed Node.js with Nginx (I think it comes with, but might be Apache).

Hi @k0ala

Something is already running and listening on port 3000 of the IPv6 interface. Run this command to list the services running:

sudo lsof -iTCP -sTCP:LISTEN -P
