Jenkins (windows) on AWS works fine on localhost:8080, but not reachable from outside

I installed Jenkins on an AWS instance along Apache (Bitnami WAMP stack) on a windows machine

Apache works great and can be contacted under http://locahost internally and http://x.x.x.x (my own IP) externally

Jenkins works great under http://locahost:8080 internally but does not work with http://x.x.x.x:8080 externally

I have opened an inbound TCP rule for port 8080 on the security group on AWS

I opened the jenkins.xml config and launched it each time with following parameters

--httpListenAddress=0.0.0.0
--httpListenAddress=x.x.x.x

I read that i should change the $HTTP_HOST variable, but not sure where i should do that on a windows machine

This is really frustrating me
