Arduino Uno R4 Wifi and WiFiClientSecure

Hi @attiliocapocchiani.

Please add a reply here on this forum thread to tell us which library and where you got it from.

If you installed the library from Library Manager, then we need the full and exact name of the library, as shown in the Library Manager listings.

If you downloaded the library from the Internet, then provide a link to the page you downloaded it from.
