    Update changed to AES-256-CBC and packet errors are gone but still no local access.

    Hi,

    I have a two openvpn servers running on pfsense, UDP and TCP, both servers connect successfully to client. But I am not access local network or local ip address on UDP Server. On TCP server it's all working fine. Help Needed

    Note : In the logs it says client disconnect, but on client side connection get shows as still connected.

    Thanks,
