Connect Naim Unity Star with Roon

I have Roon version 1.4 (build 310) stable /64bit)
Operating system: Windows 10 PC: Razer Blade Pro
The music is stored on a SD card in the Naim Unity Star
I am not able to connect the Naim Unity Star with the PC.
When I try as shown

I get the following

I did no proper network setup. I just plugged in router and PC (connected by ethernet cable) The Unity Star is connected by wifi.
Resetting the network didn’t help.
Please give me some advice how to connect properly the Unity Star to the PC to be able to run Roon

You need to be able to connect to this from your PC or it will not work in Roon. Ask the Naim support people how to do that.
