Webpage not available ... net:ERR_CLEARTEXT_NOT_PERMITTED

I made a simple app with a webview, but when it is trying to request the below url the webview show this message:

Webpage not available

The webpage at http://ofertas.cu/ could not be loaded because:

net: ERR_CLEARTEXT_NOT_PERMITTED

Nevertheless that url is ok

You need to use https or explicitly allow a specific domain.

Not working with off line file (version 3661)

webView_home:request( “build/home.html”, system.DocumentsDirectory )

work in simulator but not work on device

PS: old version of solar 3645 work perfect, Google store not accept version 3645 (API) and non submit my app

Any idea
Regards

It’s being fixed and there’s a temporary workaround.

Solved!
Thank you so much guys, very kind and helpful.
