Apple ID could not sign in

Hey, today I realized that I can't download anything from the App Store. I was trying to download a few apps and it asked me to enter Apple ID password in order to use finger print. However, after I entered password, the app wasn't downloading and I could try to download it again and again. So, I signed out from App Store and now it is impossible to join. I write the username and password and it shows that "could not sign in". I tried literally everything (network settings reset, new password and etc). What can be the problem and how to solve it?
