VueRouter pages not found after reloading on apache - vue.js

Question

I'm having this issue: when I reload the vue app on the homepage everything works quite well.
When I reload the page on another sub-site, the page shows a 404.
I'm using the router module within my project. I tried adapting the vue.config.js and setting the publicPath to '/' and to ''. When setting it to '/' i cannot replicate the issue locally. when the Path is set to '' I get the same error locally and on apache.
I tried applying some redirect rules and conditions but those which I found online which solved the same issue don't work.
I tried to use a catchall route in my router without success.
Anyone having simular issues? thank you!
Router
import { createRouter, createWebHistory } from 'vue-router'
const routes = [
{
path: '/',
name: 'home',
component: () => import('../views/Home.vue')
},
{
path: '/contact-imprint',
name: 'contact',
component: () => import('../views/Contact.vue')
}
]
const router = createRouter({
history: createWebHistory(process.env.BASE_URL),
routes
})
export default router
vue.config.js
const { defineConfig } = require('#vue/cli-service')
module.exports = defineConfig({
publicPath: '/',
transpileDependencies: true
})
apache config

In case it's not enabled
sudo a2enmod rewrite
add rewrite
<Directory /var/www/domain/>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]
</Directory>
and restarting services apache2 restart helped me to solve the issue.
