Inertia SSR start troubles

Hello, so I finally managed to get almost to finish when starting Inertia SSR, but I got stuck at this at the end:

php artisan inertia:start-ssr
Starting SSR server on port 13714...
Inertia SSR server started.

but when I start to actualy interact with the page

my ssr.js

import '../css/app.css';

import { createInertiaApp } from '@inertiajs/vue3'
import createServer from '@inertiajs/vue3/server'
import { renderToString } from '@vue/server-renderer'
import {createSSRApp, h, onMounted, ref} from 'vue'

import {createPinia} from "pinia";
import {createHead} from "@unhead/vue";
import { ZiggyVue } from '../../vendor/tightenco/ziggy/dist/vue.m';

const head = createHead()
const payload = renderSSRHead(head)

const CTAModalOpened = ref(false);
const SearchBarOpened = ref(false);
const pinia = createPinia();

createServer(page => {
    createInertiaApp({
        page,
        render: renderToString,
        resolve: name => {
            const pages = import.meta.glob('./Pages/**/*.vue', {eager: true})
            return pages[`./Pages/${name}.vue`]
        },
        setup({App, props, plugin}) {
            const Ziggy = {
                ...props.initialPage.props.ziggy,
                location: new URL(props.initialPage.props.ziggy.url)
            }

            return createSSRApp({render: () => h(App, props),})
                .use(plugin)
                .use(ZiggyVue, Ziggy)
                .use(head)
                .use(pinia)
                .provide('cta_modal_opened', CTAModalOpened)
                .provide('search_bar_opened', SearchBarOpened)
        }
    })
})

vite.config.js

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import vue from '@vitejs/plugin-vue';
import path from 'path';

export default defineConfig({
    plugins: [
        laravel({
            input: ['resources/css/app.css', 'resources/js/app.js'],
            ssr: 'resources/js/ssr.js',
            refresh: true,
        }),
        vue({
            template: {
                transformAssetUrls: {
                    base: null,
                    includeAbsolute: false,
                },
            },
        }),
    ],
    build: {
        target: 'esnext'
    },
    ssr: {
        noExternal: ['@inertiajs/server'],
    },
    resolve: {
        alias: {
            ziggy: path.resolve('vendor/tightenco/ziggy/dist/index.es.js'),
            ziggyVue: path.resolve('vendor/tightenco/ziggy/dist/vue.es.js'),
        },
    },
});

any suggestions?
