Why can't my Android phone connect to VPN via PPTP or L2TP?
Applicable Products
Android 12 or later
Root Cause
Starting with Android 12, Google does not provide built-in support for the L2TP and PPTP VPN protocols. This change in the Android operating system means these older protocols are no longer available for VNP connections.
Solution
To establish a VPN connection on Android 12 or later, you need to install a suitable third-party VPN application on your mobile device.
