LMS BBC iPlayer radio not working with VPN on Windows 10 in London

Hi - does anyone know how to get BBC iPlayer radio working with a VPN (e.g. CyberGhost)?

- CyberGhost is meant to work with iPlayer but the radio doesn't work. But that should be irrelevant since I have tried adding the following exception URLs (amongst others) which bypass the VPN altogether. But this doesn't work either:
- a.files.bbci.co.uk
- a.files.bbci.co.uk
- radio-service-information.api.bbci.co.uk

- The iPlayer Live Stream Preference is set to HLS->DASH->MP3->FlashAAC

Or, put another way, does anyone know a VPN that will work with BBC iPlayer radio / SB3?
