Problems adding source on Cydia

Hi guys,
I’m new here and need some help. I recently subscribed to Cydia VIP because I want to download Kodi on my iPad Pro. The software is up to date, iOS 10.3.
On the Kodi wiki page it says to add the following source to Cydia; http://mirrors.kodi.tv/atp/ios/
When I try to add this it says ‘invalid’ and not recognised by server.
I’m not hugely technological, but know my way round the iPad. Can anyone help me please?

Thanks
Pat
