Inspecting API Calls

Hello Everyone, I am following mosh tutorials and I’m on video inspecting api calls.
I’m unable to connect API inspector with my mobile. I’m using iPhone 7 Plus and Samsung Galaxy S8 plus. Android is connected through wire and 7 plus is connected through WiFi. I’m not using any emulators.
Here is what API inspector shows.

And here is what localhost shows.

Thanks in Advance.
