I have troubles installing lets encrypt certificate to use it when connecting to SSL Gateway.I've downloaded Lets encrypt R3 certificate (signed by ISRG Root X1, pem), but have no option to install it as VPN and applications certificate in Samsung running android 13 version. In previous versions you could choose. Any idea what to do with it? When I try to install it manually as VPN and application cert, it fails.
We dont have private CA. So far it all worked after installation of intermediate certificate but now I can only use it as "Wifi" certificate and not VPN. Iam using Forticlient on android.
