Impossible to connect to BattleNet [Solved]

Hello all,

I have a strange bug since this morning. When I try to login to battlenet in the starcraft homepage, after waiting the loading popup I get redirected to the login page.

No error message is show.

I have already tried the basic steps oulined here: Blizzard Support - Connection Troubleshooting

EDIT:
It works now!

No idea why.
