Rails binding to 'ip':3000 is giving me connection timeout

Ruby on Rails Ubuntu 16.04

Hi im following this tutorial

https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-puma-and-nginx-on-ubuntu-14-04

except that im using Ubuntu 16
The problem is after i bundle install my app, and following the

RAILS_ENV=production rails server --binding=server_public_IP

and try to access it via web app, all i get is errconntimeout

my app is indeed running, and this is what it shows

=> Booting Puma
=> Rails 5.1.4 application starting in production 
=> Run `rails server -h` for more startup options
Puma starting in single mode...
* Version 3.10.0 (ruby 2.4.1-p111), codename: Russell's Teapot
* Min threads: 5, max threads: 5
* Environment: production
* Listening on tcp://my.ip:3000
Use Ctrl-C to stop

i only followed the instructions on the tutorial and im not yet installing nginx.
Im also quite new on this stuff, i had to rebuild my droplet cause i thought i broke something on my first run as i really can't see my app and now im quite loss

this was also my netstat
