[dydhub]

When I tried to connect, I cannot connect，Log display:

Can you help me?

Sorry to inform you that this repository is not being maintained. This is only a wrapper of LegacyVpn in the system, please try to add your VPN profile in the Settings and test whether it works. Racoon is an IPSec key exchange utility, but in this mVpnService.java#L55, hard coded plain PPTP type.

Thank you very much for your reply. The previous question did not appear again, but it appeared:

java.lang.IllegalStateException: KeyStore isn't unlocked

I want to create a standalone VPN client to build a pptp/L2tp connection, but Android's VpnService doesn't seem to help me. Do you have any ideas?
