Public bug reported:
I import MyConnection.ovpn file.
In this file there is connection configuration with non usual used fields, eg.:
"data-ciphers" field.\
When I'm checking this connection by command:
nmcli connection show MyConnection
there is field: "vpn.data"
vpn.data: ca = /path/MyConnection-ca.pem, cert = /path/MyConnection-cert.pem,
challenge-response-flags = 2, connection-type = tls, data-ciphers =
AES-256-GCM:AES-128-GCM:AES-256-CBC:AES-128-CBC, dev = tun, key =
//path/MyConnection-key.pem, ns-cert-type = server, remote =
vpn.myserver.com:1194, ta = //path/MyConnection-tls-auth.pem, ta-dir = 1,
tunnel-mtu = 1500
After I change anythig in this connection via Gnome NM GUI, eg, check checkbox
"Use this connection only for this network" (or something, I'm translating from
my national language).
vpn.data field changes:
vpn.data: ca = /path/MyConnection-ca.pem, cert = /path/MyConnection-cert.pem,
cert-pass-flags = 0, challenge-response-flags = 2, connection-type = tls, dev =
tun, key = /path/MyConnection-key.pem, ns-cert-type = server, remote =
vpn.myserver.com:1194, ta = /path/MyConnection-auth.pem, ta-dir = 1, tunnel-mtu
= 1500
There is no more "data-ciphers" parameter and I can't connect.
My only change is set checkbox "Use this connection only for this network".
If I change connection name, I have this same effect.
