How to connect socket.io to express when deploying to ZEIT?

Question

Node.js

Hello everyone, the question is, how to connect socket.io to express when building and deploying to ZEIT through now? On local in development mode, everything works.
I use Next.js + Express and upload it all to ZEIT.
now.js

"builds": [
      { "src": "server/**/*.js", "use": "@now/node" },
      { "src": "package.json", "use": "@now/next" }
    ],
    "routes": [
      { "src": "/api/(.*)", "dest": "/server/src/server.js" },
      { "src": "/socket.io/(.*)", "dest": "/server/src/server.js" },
      { "src": "/(.*)", "dest": "/$1" }
    ]

server.js (socket connection)

const _server = server.listen(8080, (err) => {
        if (err) throw err
        console.log('Server is started :)')
    })
    
    const io = socketIO(_server, { serveClient: false });

client

import io from 'socket.io-client';
const socket = io('https://url....', { secure: true });

After refreshing the page, sometimes everything works for a couple of seconds, but then in the console there are errors

No way.
ZEIT is serverless, it will not connect to sockets.
