Using same config file on Mac and Windows with no issue. Using same certificates. iPad is on 10.3.1 and OpenVPN is 1.1.1

Thanks for any help on why this error is occurring. Hoping someone else has seen this

The error is

Code: Select all

AES-256-OFB: not found [ERR]
so try AES-128-CBC

probably iOS openssl library doesn't support that cipher
if your server is running openvpn 2.4 you can use --ncp-ciphers option
