No internet on emulators with API 19 or lower

I am having problems getting emulators with Android versions prior to API 19 (including 19) to connect to the internet. Emulators working with newer versions connect just fine. There is no connection at all, it is not that the application cannot access the Internet, nothing in the device can. Mobile data turns on and the 4G (or 3G) icon is displayed.

I've tried different devices but the problem seems to be with the Android version itself. I have also tried deleting and re-creating the device. Uninstalling and reinstalling the emulator, reinstalling android studio, reinstalling the SDK, and trying to force 3G are also useless.

Sorry if I am not specific enough or provide more information than this, but I cannot do more and I have not found anything on the internet that helps me.

Is there a reason for this?

Thank you in advance
