ERR_CONNECTION_REFUSED on fresh VestaCP installation (Ubuntu 14.04.05)

[ArchLinuxAdmin]

I was trying out VestaCP on my home desktop, so I did a fresh install of Ubuntu for it, and I installed VestaCP, but I keep getting that error every time I try to connect to it using my IP (122.176.130.188:8083). I've enabled Port forwarding for that port. Any ideas?
