Google Assistant SDK: I can't authenticate my Google account with Google Assistant

Hi there,

I am trying to configure “Google Assistant SDK” following the official documentation. I have done all the steps and managed to start the Add-on in HA. But I have problems in the last step. I can’t authenticate my Google account with Google Assistant. I get an error when trying to get the code from Google (See screenshots). Any idea how to solve it?

Thanks!

Regards,
