Options error: data-ciphers (2.3.6)

[bolin3000]

Had to renew my certificate & now get this error:

"Options error: Unrecognized option or missing parameter(s) in ...ovpn:21: data-ciphers (2.3.6)
Use --help for more information."

Am running openvpn-2.3.6 on a Linux box beyond upgrade.

conf looks like this:

"client
dev tun
remote xxx.org 443
resolv-retry infinite
nobind
persist-key
persist-tun
auth-nocache
verb 3
explicit-exit-notify 5
push-peer-info
setenv UV_IPV6 yes
remote-cert-tls server
comp-lzo no
#ciphers AES-256-CBC
data-ciphers AES-256-GCM:AES-256-CBC:AES-192-GCM:AES-192-CBC:AES-128-GCM:AES-128-CBC
data-ciphers-fallback AES-256-CBC
proto udp
auth SHA512"

Very thankful for any ideas!

Have a look at the available options of OpenVPN 2.3 for appropriate old variants (loosely) matching data-ciphers.
