I am trying to start nodejs server and receiving the following error no matter which port I choose to listen from:
root@nodejs-s-1vcpu-1gb-fra1-01:~/SalahTimes.PL# node server.js
events.js:292
throw er; // Unhandled 'error' event

Hi there,
It looks like port 80 is already being used by another service. You can check which service exactly by running the following command:
You can not have more than 1 service listening on the same port.
What you could do is change the Node application port to 8080 for example so that it could start as normal.
I would also suggest following the steps here on how to prepare your Node application for production:

Hope that this helps! Regards, Bobby
