VM Not Showing in Panel

[ktask]

Have a VM with a public IP address running a couple of Moodles in subdiretories.  VM uses Webmin as a panel on port 8080.   Can nmap scan the IP and see that port 8080 is open, but cannot connect to that port.   I can connect to the site static page and to the moodles hosted on server.

Is there a way to reboot server ... could be that I inadvertently added an IP address to a firewall drop zone that is not permanent ... rebooting will clear the list.

Thanks, in advance, Ken
