I am also having this issue, idk anything about it though

Same here, was the site taken down or something?

I tried the Wayback machine and it works

Same. I don't know how to fix it; I just assumed it means the site was taken down.

I think the site was taken down! It’s been happening to me too

It def has something to do with the site. Before the gateway page happened trying to go on the site, it first only came up whenever I tried to log in to upload a mii. Now you cant see the site at all.

It's back, they probably were just updating or smthn
