Post by ak4490 » Fri Feb 12, 2021 5:22 am

I create a openvpn tunnel, and it works well on my android phone. however. The OpenVPN application on windows 10 with same config file cannot connect to vpn server. The log file always shows:transport eror, socket_protect_error (TCPv6). Is there anyone know the solution? Thanks
