Why my Mi Fit app doesn't work? Please help

[Pdomy]

I just bought a Mi Band 4 but when I try to register in the Mi Fit application, after I have to select the country, I press "next" and it says "Can't connect to network, try again later". I've been trying for a few hours but I can't figure out what might be the problem, I tried selecting other countries, tried to login with google account but nothing works, please help.
