The game says the QR code doesn't belong to the game. I know it is not the case since the pelliper background is visible. I'd suggest taking another screenshot (maybe the lighting in the one you posted is causing some sort of inconsistence).
Also, the perspective seems strange: the left half seems closer while the right one is farther. Maybe it's affecting as well.
By the way, the code isn't working too and I've used the "circle inside a circle" as we instructed.
What about that? Take a screenshot of the QR codes and, if possible, the screen with the password
