The same things happening to me, restart your router, and it should work. And after that it’ll only work until you switch to sysnand vice versa. Then you have to restart the router again.
I am trying to hack Fire Emblem Warriors on my 2DS XL, I have been trying to get it to work, but I need some extra help figuring it out. I have HEX codes, and a possibly outdated plugin, but I dont know how to implement them
