After you have installed and configured the Orchestrator appliance you might start regretting some of your configuration options.
To change the IP address settings or appliance name for Orchestrator use https://<ip>:5480 and the “root” login (the password was set when you deployed the OVS/OVF) to connect to the management page for the appliance.
Select Network then Address
In my experience changing the IP and the hostname needs to be a two step process (one, then the other).
After applying the changes reboot the appliance and ensure proper function with the changes.
