Opal : can't get OpenVPN client connect to server

Hello,

When I try to connect my Opal’s OpenVPN client to my home router’s OpenVPN server, it stucks for while, then cancels.

Here is the openvpn config from home router :

remote xxx.xxx.xxx.xxx yyyyy
float
nobind
proto udp
dev tun
sndbuf 0
rcvbuf 0
keepalive 15 60
comp-lzo adaptive
auth-user-pass
auth-nocache
client
auth SHA256
data-ciphers-fallback AES-256-CBC
remote-cert-tls server


-----BEGIN CERTIFICATE-----
Bla bla bla
-----END CERTIFICATE-----


-----BEGIN CERTIFICATE-----
Bla bla bla
-----END CERTIFICATE-----


-----BEGIN PRIVATE KEY-----
Bla bla bla
-----END PRIVATE KEY-----

Where xxx is my wan IP (static, no need of DDNS) and yyyyy a dedicated VPN port (open in Opal’s fw). Opal is connected to internet with my Android phone tethering.

This openvpn config works fine with OpenVPN client installed in Windows 10.

Can anybody help fixing this issue ?

What’s the firmware version? Could you paste screenshoot and log?

Firmware is 3.212

Thanks to working vpnbook client configs, I groped for the explanation : data-ciphers-fallback parameter is inappropriate. Once replaced with cipher, the connection is OK.

For instance, I don’t know where this bad parameter comes from … My home router uses cipher in exported openvpn files.
