Error 42 keeps popping up

So since about a couple of hours ago, I've been getting error 42. I've tried restarting my modem, my computer, closing the GW2 client for a few minutes, changing my DNS to an open one. Nothing seems to work, kinda stumped now.

I can log in and play, but I cannot actually use the trading post or join a party or squad, and the error 42 message comes up every few minutes.
