Error 502 trying to use Laravel Sanctum with custom model – Nginx

I’m using Laravel sanctum to authenticate my API, but i’m not using the default laravel User model, I’ve built a model to separate my App customers in another table called Customer. To this to work I did the alterations bellow

Custom model Customer.php

<?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;
use IlluminateFoundationAuthUser as Authenticatable;
use IlluminateNotificationsNotifiable;
use LaravelSanctumHasApiTokens;

class Customer extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable;

    protected $fillable = [
        'first_name',
        'last_name',
        'email',
        'password',
        'cpf',
        'phone',
        'postcode',
        'address',
        'number',
        'neighborhood',
        'city',
        'state',
        'country',
        'store_front_id'
    ];

    /**
     * The attributes that should be hidden for serialization.
     *
     * @var array<int, string>
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast.
     *
     * @var array<string, string>
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}
