When I try to sign into my account it goes to a website that is a deleted website

There was a bug where I couldn't join a realm and I looked up how to fix that and it said to sign out and sing back in so I signed out and I pressed sign in and it to me to like the minecraft page and I pressed sign in again and it took me to a website that said this site cant be reached and I've re-started my phone and minecraft and it still isnt working
