Hi there @Thal82
Welcome to our Community and thanks so much for your first post - it is rather an odd one with you being at home! Usually you only get that message if in the EU (now we have left) or if you are trying to view a channel like BBC Scotland whilst in Wales for example.
I have located your account from here and all looks to be in order. The Hub not been rebooted in around 50 days or so so might be worth doing a quick reboot there. Both boxes have been rebooted within the week so that's ok.
Please can you reboot the Hub and then please try and log in on our website on either a PC or Laptop and see if you get the same message? Virgin Media TVGo
If you could also check via the app on a data connection and see if you get the same error message that would be great.
Keep us posted
