I usually connect it in the following way using Openvpn 2.x.  
`sudo openvpn <VPN_FILE.ovpn>` then it will prompt for the credentials.

Here is the INE video on LAB VPN connectivity.

Hi,

OpenVPN3 currently lacks of support for TAP or bridged connections. Use the latest 2.X version that can be downloaded from [Community Downloads | OpenVPN](https://openvpn.net/community-downloads/) or installed via your package manager. If you need further assistance, please provide information about the OS you are using and we will be able to guide you trough the installation process.

Thanks!
