Netflix issue

[RyanC90]

I was watching a programme on Netflix yesterday on my sky box. Came back this morning to watch it and it just disappeared along with other random content. I contacted Netflix and they said the programme was still available in my country. When I try and cast from my phone to sky box to watch the programme it says I'm using a VPN which I'm not and am connected to the same WiFi. How do I get mu content back as Netflix are saying its this end not theirs.
