Application.IsOnLine on wifi without internet

Hi, I discovered Application.IsOnLine is True if WiFi is power-on BUT if wifi is on and i'm connected to a wifi without internet access IsOnline is always true !
There is anyway to check if there is or not a internet connection ? because i must connect to a device like ESP32 used as AccessPoint that can't connect to internet.

We expose what the browser API reports. Sadly, beyond this, we do not have a different way to report online state. I think you'll need to perform a test request to the server you need and interpret the result of this request.
