Android - Firebase login via Google-auth

Question

I want to log in using google, but I still get task.isSuccessful = false. I cannot go through this condition

I will also add that on firebase there is added SHA-1 and updated JSON file. Any suggestions on how to solve this? :)

My code

class GoogleAuth : StartActivity() {

    private lateinit var firebaseAuth: FirebaseAuth
    private lateinit var googleSignInClient: GoogleSignInClient

    private companion object {
        private const val RC_SIGN_IN = 100
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.web_client_token_id))
            .requestEmail()
            .build()

        googleSignInClient = GoogleSignIn.getClient(this, gso)

        googleSignIn()
    }

    /**Google SignIn*/
    private fun googleSignIn() {
        val signInIntent = googleSignInClient.signInIntent
        startActivityForResult(signInIntent, RC_SIGN_IN)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)

        if (requestCode == RC_SIGN_IN) {
            val task = GoogleSignIn.getSignedInAccountFromIntent(data)
            val exception = task.exception

            if (task.isSuccessful) {
                try {
                    // Google Sign In was successful, authenticate with Firebase
                    val account = task.getResult(ApiException::class.java)!!
                    Log.d("GoogleSignInActivity", "firebaseAuthWithGoogle:" + account.id)
                    firebaseAuthWithGoogle(account.idToken!!)
                } catch (e: ApiException) {
                    // Google Sign In failed, update UI appropriately
                    Log.w("GoogleSignInActivity", "Google sign in failed", e)
                }
            } else {
                Log.w("GoogleSignInActivity", exception.toString())
            }
        }
    }
}
