Static IPS ports not connecting

[zustudios]

I installed Proxmox 5.I have 5 static ips. I'm running 1 ip for the host,2 webservers (ubuntu 16.04 ispconfig 3.1),1 windows 7,1 cloudserver (ubuntu 16.04 nextcloud).
I have internet connection on all machines. My isp said all ports are open by default on static ips. But when I go to my ip:8080 I get no connection. when I go to my ip:80 I get a connection. What could be blocking my connections on some of my ports?

If you didn't activate the PVE firewall, then check your router for its firewall or the VM in question, it may have a firewall or the service isn't listening on that specific port.

What do you mean? Do I check on host or vm? I only installed proxmox on the host. I didn't setup any firewall. I have the ufw on the vm but the ports are still closed.
This is a fresh isp setup a fresh proxmox install and a fresh ubuntu 16.04 install. I call the isp and they said all ports are open on my static ips
What are the commands so I can check?

Inside VM check if service on port 8080 is running.

$ sudo netstat -ntlp | grep :8080
