Friend safari stuck at rainbow screen

Hi all,
I’ve recently started playing and i wanted to try the friend safari out.
I can connect perfectly with the GTS trading tool and that works fine.
But whenever i want to try the friend safari. I can login. I can put a name up of a friend.
But then i’m stuck at the rainbow screen and if i wait long enough it just says “you are disconnected”.
I’m on 1.2.3 and also restarted my pc/game a couple of times but nothing works…
Any ideas?
