"Sorry, we were unable to log you in." When launching Overwatch

It says this every time I try to log on. It’s been going on for two weeks and I’ve already tried reinstalling, and read multiple threads. No help. I can easily log onto my alt account, the problem has never occurred there, so it’s not an IP or network thing. This is the first time I’ve experienced something like this. Please help me, I would love to play again.

I have the exact same problem for over a week now, and nothing i can do about it. Blizzard?
