I can't see http://ip:8080

I install ispconfig3, in a VPS with Centos 5.5 86.
I reached to see the control panel and change my language

But after the system don't run.

I can't see http://ip:8080
I can't see http://ip

But I can use the ip to access by ssh.

I guess that need to install something, how I can know that I need to install?

Gracias y saludos
