Firebase Authenticator Error

Hello everybody,
I know that there are already publications about this error, but none have worked for me and they are already closed.
When using Firebase Authenticator I get the following error:
“For a custom firebase host you must first set your authenticator server before using autentication features!”

I had already done that and it still doesn’t work.

What do You try ?

I already tried to change the server location to USA and added all the certificates to Firebase.

So, show us your blocks and configurations

Ok, it’s a little messy, but, here it is.
