I get disconnected

I haven't logged into the game for about a week, and now when I try to buy items from trade, I get disconnected from the server in about 3 out of 10 cases. Has anyone else experienced something like this? For what reason does the game simply not let you enter some hideouts? Also, after entering someone else's hideout, the trade window with Ange just doesn’t open for me — I have to manually look for him around the hideout (best wishes to everyone who hides him on purpose) and buy the items that way
