Cannot open 8080 port on EC2

I use AWS Ubuntu Instance and try to open port 8080. This is my “Security Groups” settings:

ec2 image

I have added port 8080 to iptables:

sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http-alt

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Firewall is disabled:

sudo ufw status verbose
Status: inactive

nmap:

nmap localhost

But port still seems to be closed when I use server IP:

nmap ec2-18-184-30-11.eu-central-1.compute.amazonaws.com

What should I do to open port 8080?
