How to set debug host and port on android 8.1

Question

I'm debugging my app via WiFi. It installs successfully but I got a red screen with an error:

The documentation says that I should set debug host and port but there is no "Debug server host & port for device" menu entry. Also, my problem is similar to this issue.

bring up the react native menu that is referenced in the link below
start with debugging turned off (the menu should show debug JS remotely and not stop debugging).
if the app is running with debugger, configure the debugging host and port: click on dev settings and type localhost:8081.
now try to run the app while npm start or yarn start is running in the host's terminal window.

This is the menu:
