502 error when running Node app with PM2
I have followed the instructions laid out in this tutorial https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-18-04.
I can successfully run my application using
$ sudo node app.js
and access it in my browser.
However, when I run the app using
$ pm2 start app.js
it says the app is running but when I access it in the browser I get a 502 Bad Gateway error. Any ideas?
