Hello I am running AWS EC2 on centos. I have installed Webspehre liberty and started it.
When I run netstat -an | grep 9080
I see
tcp 0 0 ::ffff:127.0.0.1:9080 :::* LISTEN
But when I go to my Public DNS: ec2-XX-XXX-XX-XXX.us-east2.compute.amazonaws.com:9080 in my web browser I get ERR_CONNECTION_REFUSED
In my security groups I have allowed Inbound traffic on all ports from anywhere Port: 0 – 65535 Source: 0.0.0.0/0
When I wget ec2-XX-XXX-XX-XXX.us-east2.compute.amazonaws.com:9080 on the server I get the home page downloaded onto the server, so the site is up but just not publicly accessible.
Also when I run
#service iptables status
iptables: Firewall is not running.
So the firewall is off.
What am I doing wrong?
Thank

The address
::ffff:
is a subnet prefix that indicates an IPv4 address embedded in an IPv6 address. Thus,::ffff:127.0.0.1:9080
indicates your service is only listening on the local loopback address 127.0.0.1 (localhost) and is therefore not accessible via your external address.To make this work you need to cause your service to listen on the appropriate external address.
