Can you fix error 2401 on mobile with 5G? – Genshin Impact Review

I would give this game a 3 out of ten. I really love the game and it’s mechanics. I love everything about it but whenever I try to get in( I’m a mobile player) I get error 2401. I have 5G network and this just started happening. It used to work perfectly fine without WiFi but now I have to use WiFi every time I play no matter where I am even if I’m in my.
