No errors, but no connection after upgrade

[lbm-services]

I switched my app to vite and upgraded packages. Since then I have no connection to my socket.io server. The funny thing is: if I enter a WRONG port, I see it trying to connect, with the right port (80) it simply does nothing. The problem seems to be my socket-io-actions are in a vuex store. Is there a way to use vue-socket.io-extended with Pinia?

main.js

import VueSocketIOExt from 'vue-socket.io-extended';
import io from 'socket.io-client';
import store from './store/index.js'
var ip = '192.168.2.230';
// if on dev use ip
var host = 'http://' + (document.location.port == 5173 ? ip : document.location.host);
const socket = io(host);

Vue.use(VueSocketIOExt, socket, { store });
