Hi everyone.

Maybe someone here can help me, google was no help.

Here's the issue:
I've got a clean install of Tumbleweed on my machine and wanted to add a VPN connection. I imported the certificate and so on, saved, and when I tested the connection it worked fine.
After a reboot this connection is no longer working, however. When I try connecting I get an error: "The service providing the VPN connection was stopped."
According to services-manager the NetworkManager service is running without issues.

Any help would be appreciated. Thanks

The error sounds to me like you don't have the package NetworkManager-openvpn installed.
