Try to set on you index.js or app.js server side this:

  app.use(function(req, res, next) {
  res.header('Content-Type', 'application/json;charset=UTF-8')
  res.header('Access-Control-Allow-Credentials', true)
  res.header(
    'Access-Control-Allow-Headers',
    'Origin, X-Requested-With, Content-Type, Accept'
  )
  next()
})

and in you client site add options like this:

let axiosConfig = {
  withCredentials: true,
}

export async function loginUser(data) {
  try {
    const res = await axios.post(
      `${URL}:${PORT}/${API}/signin`,
      data,
      axiosConfig
    )
    return res
  } catch (error) {
    console.log(error)
  }
}
