Connection and Log-In error

Hey,

Today I encountered some problems connecting to multiplayer servers (always showing that error message "Unable to login: Please try restarting your game and launcher") and my friends recommended logging-in to the official website and trying again afterwards. I entered the correct credentials, but somehow captha was bugging and when it finally let me through the profile screen wouldn't load. After reloading the page, I was always forced to enter the credentials again, but with no success.
