Doesn't start session

Dear monjang please I need your help urgently, I CAN'T LOG IN TO MINECRAFT WITH XBOX ACCOUNT

If I am going to log in, everything is normal, it goes out there, we are going to log in, I put the button and a problem appears which is that the page is badly written according to what it says there, which my friends did not work. Please I need you to ask or I won't be able to play with friends or servers
