Restclient to VirtualBox w/ win10 VS17 issue, Help!

So im trying to call a route using my restclient(postman/insomnia/etc…)

My vs17 is running a project as usual and i can make calls on the guest VM.
however on my host linux system i am unable to make the call using:
localhost && as suggested.

I’ve also tried bridged, turning off win guest firewall.

I’m at a loss, please help!
