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?

Hi there @digitaloceanjd,
It sounds like that the application might not be starting, what happens if you try to get information for your application with:
- pm2 info app_name
And also try to use the pm2 monit command to check the status of the application.
I would also recommend checking your Nginx error logs:
tail -100 /var/log/nginx/error.log
Another thing that I could suggest is making sure that your application is listening on the correct port:
sudo netstat -plant
Also, as a side note here is also a quick video on how to deploy Node.js with PM2, Nginx as a reverse proxy, and Cloudflare for SSL termination:
Let me know how it goes! Regards, Bobby
