Alexa Media Player integration failure

When trying to install the Alex Media Player and follow the authentication steps I get to the final stage where it opens through my internal IP adres the Amazon login page where I select existing user and there it gives already an OTP but if I press ok or even try to use a generated OTP from my authenticator app it syas failure and I have to start all over again. I already have 6 apps now in my Amazon 2SV methode but cannot remove some of them. Where do I go wrong here?

I put on a new Home Assistant server and also wanted to install this integration. At MIT comes the mistake that my Multi Factor Code is wrong. However, it is safe. I will watch your topic. Maybe someone has a solution to our problems. :wink:
