android marshmallow and VPN problem

I am having a strange problem. I have kodi in my laptop and in a android box running android 4.4. My family liked kodi so i bought 3 Kodi boxes running android 6.
We like to watch Brazilian TV and I use an addon called Globo.com.
I have PIa vpn connected to Brazil because without it i cannot login to globo.com.
however, all my new boxes are blocking my login into globo and i cannot figure out why. the new boxes are all different, the only thing they have in common is android 6.
Does anyone have any ideas what else can i try? i already unistall and reisntall kodi from the old and new box reinstall globo.com just to be sure i am using the same build. i do not know what else to try.
thank you for your help.[/size][/size]
