Serviio through VPN on Windows 10

Hi,
I have been using Serviio through a VPN (Cyberghost) on Windows 8.1 and it worked perfectly.
I have recently upgraded to Windows 10. Now when I'm connected through my VPN, none of my devices can see my Serviio server... It still works on Windows 10 when I'm not connected through my VPN.
The only thing that has changed is going from Windows 8.1 to Windows 10. I haven't changed any Serviio settings.
Does anyone know why I am having this problem now in Windows 10?
Thanks
