Can't join to servers

[Sentilz]

So i went to actually play minecraft like a normal person, and the thing was that i couldn't connect with multiplayer server even if i got actually cracked account, idk what is the reason that u can't log in to a multiplayer server but it's saying that i am not logged into any account something like that, and i need to restart my launcher or game even if i did, and it did nothing.
