Cannot login to my account

Hi,

I've been playing on and off for 13 years.
I came back to the game a few weeks ago linking my account to steam.
Yesterday I've played a few hours with no problem.
Today I cannot login. 
I have the right account, right password and the security key.
Everything works great for weeks.
Now since this morning I cannot login.
I tried on my laptop; same problem.
I tried on an other internet connection; same problem.
"Please confirm your login information" ; My information work fine yesterday, nothing has change on my end.

I can connect with my account and password on the swtor website; that confirm I have the right account name/password.

Please help me.

Thank you for your support.
