Redmine, AWS, Ubuntu 16.04, no outside access

Hello All.

I've tried to setup a redmine server for my work on AWS, following this guide:
http://www.untrustedconnection.com/2018/01/redmine-passenger-and-nginx-on-ubuntu.html
and with little or no errors I get thru it all.

In the end, i use lynx (textbased browser) to check that it works, and on both
127.0.0.1 and the "local" ip provieded by amazon, i get to the page.

however, when i try the "external" ip it fails, and also it fails
when i try from my local computer, not the cloud one.

any tips?

I supect its some sort of firewall-thing, and i've tried (not saying i've succeeded) to open port 80 on this virtual server

Cheers, DJ

To awnser my own question:
on the EC2thingy, find security groups, and add a port 80 one :D
