How to set up Laravel .env file to work with axios and Laravel Sanctum?

Question

I have a webapp that works with Nuxt as a frontend and Laravel as a backend and Axios as a bridge between the frontend and the backend. In local it works fine but when I go on production mode it doesn't work and I get this error:

 GET http://localhost:8001/sanctum/csrf-cookie net::ERR_CONNECTION_REFUSED

On my .env file I have this configuration:

#Backend
SESSION_DOMAIN=157.230.109.19:8001
#Frontend
SANCTUM_STATEFUL_DOMAINS=157.230.109.19:3000

And in Nuxt I have defined a plugin file called axios.js:

import axios from "axios"

export default defineNuxtPlugin((NuxtApp) => {
    // Tutte le richieste richiedono che l'utente sia loggato
    axios.defaults.withCredentials = true;
    axios.defaults.baseURL = 'http://localhost:8001'
    // axios.defaults.baseURL = 'http://157.230.109.19:8001/'
    return {
        provide: {
            axios: axios
        }
    }
})

I have to work with IP addresses because right now I don't have a domain for the application.

To replicate the error you have to go here: http://157.230.109.19/login and click the login button (the email and password fields could be empty).

On the Nuxt Plugin I have tried to change the baseUrl with the server IP address or with localhost but it doesn't work.

In Postman I have tried to call on http://localhost:8000/sanctum/csrf-cookie and I get the cookies, but when I try to call http://157.230.109.19:8001/sanctum/csrf-cookie it return 'No cookies received from the server'
