Error during LogIn (gives an Exception)

[Franco7Scala]

I have this error in the console from my android device:
Unity : Google.GoogleSignIn+SignInException: Exception of type 'Google.GoogleSignIn+SignInException' was thrown.

I have followed all the guide, and I have used web id client, and android id client and ios android client but no one seems to work!
What is the problem? why I have this issue? There is a way to get an error description more detailed?

Thanks

I get the same error, the frustrating thing is the exception msg is useless

Seem like, somethings wrong in Package Name, web client id, or SHA1 key hash
