macOS - Failed to regenerate WireGuard keys. Private key generation error: 133

    This error is caused when you attempt to connect to a WireGuard server using an old version of macOS. To use WireGuard, your device has to be running on macOS version 10.14 or later.

    Updating your macOS device to a supported version will resolve this issue. If updating is not feasible, you can continue connecting using OpenVPN or IPSec with IKEv2 VPN protocol.
