Tidal login fails

I'm all of a sudden experiencing failure to login to TIDAL. It worked yesterday, but this morning I just got an empty menu on the squeezebox, and failure to login when trying to set it up on mysb.com
I've tried changing the password on TIDAL, which didn't help. Funny thing though - on my TIDAL app on the android phone, the login also failed this morning, but a restart fixed that.

Any tips?
