I can't hear a preview VST Amp Rack effect on my guitar

I have a guitar connected into UR28M audio interface on Mic line 2.
On Cubase PRO I inserted an audio track to hear the guitar, so my problem is that I can’t hear those VST Amp rack effects without recording first and I know you can use VST Amp rack effects for live performance because i’ve seen them on videos.

If my connection is the problem, how can I connect it properly so I can hear those effects live without recording at all? :question:

Here are some images so you can see my connections.

try turning off direct monitoring under device setup.

That worked! Thanks!
