Having the same error message but different console log,
I
- setup by DNS and VPN with server.app (both services have green lights to indicate they are ready)
- imported my VPN settings to my client machine
- try to connect and receiving error message "L2TP VPN server did not respond. Try to connect again. If the problem persists, check the settings and contact the administrator"
Any help would be greatly appreciated
