If you have installed QuickBox Pro and your IP Address has changed, or you entered the wrong IP Address, you can run the following command to change the IP Address
qb fix siteroot <IP Address>
Where <IP Address> is, you should enter your new IP Address that you wish to change it too.
This will then change your IP Address of your server. You should then reboot the server for the changes to take affect.
Now you can access the QuickBox Pro Dashboard from your new IP Address.
