stronger ciphers
It would be great to allow stronger ciphers.
I tried to connect via openvpn client version 2.5.1 using AES-256-GCM as specified at https://github.com/OpenVPN/openvpn/blob/master/doc/man-sections/cipher-negotiation.rst. However, data channel cipher negotiation failed due to no cipher match. I used the following openvpn client config.
dev tun
proto tcp-client
remote 212.129.4.141 443 tcp
remote 212.83.182.127 443 tcp
remote 212.129.37.129 443 tcp
