About how to config application UI port

I try to install application server and get it success, but it seems I cannot access web ui per 8080, I looked into server:
netstat -ltupn, seems 8080 no LISTEN on TCP but TCP6 as below:
tcp6 0 0 :::8080 :::* LISTEN -

Should I change anything to enable 8080 on TCP ?

I am newer.
