OpenVPN: An error has occurred whilst trying to connect

I am using OSMC on Raspeberry Pi.
I have installed openvpn via the Brian Hornsby method. I am not a coder and the istallation took a LONG time and was very frustrating.
Connection seems to finally work OK via the terminal window.

I am stuck at the OSMC level:

‘An error has occured whilst trying to connect OpenVpn
Unable to connect to OpenVPN management interface’

Connecting to the internet using an Orange Telecom proprietary modem in France. Very good download speeds of around 40mb
As far as I know I have configured everythign according to instruction.

Any help gratefully received.

Where are you seeing this?

Clearly “at the OSMC level” this is working as it is working on the command line and OSMC is the operating system. Are you trying to connect from within kodi? Are you using an add-on?
