Why can't I access my app externally?

I installed node, deployed my app (vue.js / nuxt app) and used npm install. When I use npm start it uses nuxt start and I get the message OPEN http://localhost:3000, which seems to be correct because if I open a second terminal and use netstat -plnt I get

(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0* LISTEN -
tcp 0 0* LISTEN 13929/node
tcp6 0 0 :::22 :::* LISTEN -

I also if I use curl http://localhost:3000 in a second terminal the app seems to work. However, if I enter http://MY_IP:3000/ or http://MY_IP/ in my browers I get Unable to connect - Firefox can’t establish a connection to the server at MY_IP:3000.

Sorry, I am still quite new to this - what am I doing wrong here? Why can’t I access my app externally? Thanks for any help!

I think I found the solution. I added the following to my package.json file:

"config": {
 "nuxt": {
   "host": "",
   "port": "3333"

Apparently, as host was the problem.

A bit more info:

  • Yes this make sense. It doesn’t say in the doc you linked but I imagine you would replace the with your own droplets actual IP address too.
