Cannot travel to other players' hideout to trade with Poe2 trade website

So the trade website for poe2 has the option to travel directly to another player's hideout in order to buy directly from their stashes. But whenever I try do that the site tells me that I need to be online and in the same league. I always have the game open when I try to trade and have a lvl 52 rise of the abyssal sorceress. But nope, fuckin site tells me otherwise. I've tried logging in and out, linking my email, changing to a different league on the site. Nothing. There is absolutely nothing I can do that changes this.

Can someone please tell me how to fix this?
