Does your parents or you own a administrive blocking software, such as Quostudio?

I had acsidently downloaded it and blocked minecraft, and fixed it. If thats the case you do this...

Go to the app - Log out - Go to the website/app - Disable the protection on your device - Disable your account - Wait 1 - 2 hours for it to work

If that isint the case, You should report it to mojang with the error code you recieve (Should be near the text)
