Plasma5 and wireguard support through integrated networkmanager GUI

So basically I've been using mostly XFCE4 and Wireguard VPN worked perfectly. When I switched to Plasma5 I can no longer connect to my Wireguard server.

When I try to connect, plasma gives me this message: The device could not be configured

This is what journalctl | grep -i wireguard shows:

Jul 19 19:55:36 ERIKOARCHLINUX NetworkManager[801]: <info>  [1563555336.5583] manager: (Namai_wg): new WireGuard device (/org/freedesktop/NetworkManager/Devices/4)

I did not change any settings when I switched from XFCE. It just doesn't work!

Any ideas how to get it working?

Re: Plasma5 and wireguard support through integrated networkmanager GUI

The issue has nothing to do with your DE, it's caused by upgrading to linux 5.2: https://bugs.archlinux.org/task/63149.
