i can't login/play with my account

my minecraft account just bugged, its saying i dont have the game, but i have it. its saying i can just play the demo, and if i want to change my skin i need to buy it, but i already did it months ago. first it was saying to play offline, and then, i uniunstalled and installed the launcher again, and now is saying that i dont have the game. and when i try to acces my account page on the site, it give me a bad gateway screen. sometimes i can see my profile page, here it is. keep unsolved why this happened, but if it happens again, i already have the article. the game just recognized my account, idk what happened, but my account is working again.
