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:       :::*      LISTEN

But when I go to my Public DNS: 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:

When I wget 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?

Solution :

The address ::ffff: is a subnet prefix that indicates an IPv4 address embedded in an IPv6 address. Thus, ::ffff: indicates your service is only listening on the local loopback address (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.
