Once human ipad

So I recently bought an iPad Pro 2021 13-inch M1 chip (I wanted to be specific, so I said the whole name).

But when I try to log into my account or even play the game with a new account, it doesn't let me get in.

When you open the game, after a couple of seconds, there's an action of entering the game; it's that part I can't get past. I have tried downloading everything, but it still doesn't let me get in.

It says there is something wrong with my internet, but I for sure have a good internet connection because I do play other games.

If any of you guys had the same problem and solved it, it would help me a lot, even if it's PC or mobile.
