Hi !

I am using for 4 years a VPN provided by a french association. It has always run correctly under OpenSuse LEAP, with basic GUI configuration. See attached picture.

Since I have moved to OS Tumbleweed, I cannot connect any more to this VPN.

The openvpn log is :

Options error: You must define TUN/TAP device (–dev)

But I have defined the TUN Device in the Advanced Properties ; see attached picture

Since openvpn is a part of Networkmanager, I don’t know where I can find the .conf file.

Thanks for your help ! :handshake:

Do you still have an .ovpn for the VPN? If so, try:

sudo openvpn --config your.ovpn

That should set up your VPN connection.

If that works, try to add it as new VPN connection:

Then select Import VPN connection… at the bottom of the list and select “your.opvn” and continue the process to set up a new connection.
