has anyone else problems with logging in at bitfinex (who uses 2-FA) ?

I enter my password and then when I enter my OTP (Google Authentificator) I always get an error message
that my OTP is invalid.

Google Authentificator works fine on other websites, I just have this problem at bitfinex since today.

I also tried Google Chrome and Firefox, but in both browers I can´t manage to enter a valid
OTP password
