Vpn on, but not working

I'm currently in Greece. Have my Vpn set for London. Been able to watch I player, Itv, etc. all week. Now won't work. Says we have detected you are in another country. Any ideas? Thanks

Have you tried to change the AVG Secure VPN server location to Gotham City or Wonderland and then check if it helps?
Thank you and keep us updated.

Yes. I have tried both these locations and it is still not working on any of the streaming apps

I have tried these and none appear to be working.

Have you tried to turn off your AVG Secure VPN program and then check if you are able to access I player, Itv, etc.?
Thank you.

Yes. I have turned off secure Vpn and none of the channels work. The only one that works with the vpn on is itv.
