The Error Msg :

I was trying to implement Firebase authentication with Svelte Kit and did everything accordingly to this repository https://github.com/eraygundogmus/sveltekit-firebase-auth-example
Although it’s not working – when the login modal window is opened nothing is there, but a message saying that host 127.0.0.1 refusing connection on port 9099.
How it’s set up in firebase.json
