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 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.


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:

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
