When I try to enter with my account (I am premium) to the official page or the launcher it doesn't let me, but it let me log in on mojang.
When I try to log in the launcher, it says: Could not connect to the server.
But the internet works perfectly

And when I try to login to the official page it says: A error prevented your request from being processed. Please try again.

If anyone can help me with this, I would be very grateful.
