websocket call ticket not working

eu tentei replicar a parte do websocket, tudo funciona corretamente mas quando o usuário chama a próxima senha, o disparo do websocket conectado "call ticket" não funciona, o codigo que eu fiz é bem simples, só fiz para testar o fluxo

window.onload = async () => {

  const client_id = '2_3rj4b604e60w0ok8cckwkssw0cs4k0cco0sww48swscco44gg0'
  const client_secret = '47i7t5n2zv0g4wksoskkkww0c0ogw0s8o8sc48co4sggkwk08o'
  const username = 'admin'
  const password = '123456'

  const api = axios.create({
    baseURL: 'http://localhost:8080/api'
  })

  let access_token
  let refresh_token
  let socket

  async function auth() {
    var params = new URLSearchParams()
    params.append('grant_type', 'password')
    params.append('client_id', client_id)
    params.append('client_secret', client_secret)
    params.append('username', username)
    params.append('password', password)
    return (await api.post('/token', params)).data
  }

  async function refreshToken() {
    var params = new URLSearchParams()
    params.append('grant_type', 'refresh_token')
    params.append('client_id', client_id)
    params.append('client_secret', client_secret)
    params.append('refresh_token', refresh_token)
    const refreshResponse = (await api.post('/token', params)).data
    access_token = refreshResponse.access_token
    refresh_token = refreshResponse.refresh_token
  }

  async function fetchMessages() {
    await refreshToken()
    const id = 1 //unidade
    const config = {
      headers: {
        Authorization: 'Bearer ' + access_token
      },
      params: {
        servicos: '1,2'
      }
    }
    const messages = (await api.get(`unidades/${id}/painel`, config)).data
    console.log(messages)
  }

  function doConnect() {
    const url = `http://localhost:2020`
    console.log('[websocket] trying connect to websocket server: ' + url)

    socket = io(url, {
      path: '/socket.io',
      transports: ['websocket'],
      secure: true,
      timeout: 2000,
      reconnection: true,
      reconnectionDelay: 1000,
      reconnectionDelayMax: 5000,
      reconnectionAttempts: 3
    })

    socket.on('connect', () => {
      console.log('[websocket] connected')
      socket.emit('register panel', {
        unity: 1,
        services: '1,2'
      })
    })

    socket.on('disconnect', () => {
      console.log('[websocket] disconnected!')
    })

    socket.on('connect_error', (evt) => {
      console.log('[websocket] connect error', evt)
    })

    socket.on('connect_timeout', () => {
      console.log('[websocket] timeout')
    })

    socket.on('reconnect_failed', () => {
      console.log('[websocket] max attempts reached, ajax polling fallback')
      socket.open()
    })

    socket.on('error', (evt) => {
      console.log('[websocket] error', evt)
    })

    socket.on('register ok', () => {
      console.log('[websocket] painel registered')
      fetchMessages()
    })

    socket.on('call ticket', () => {
      console.log('[websocket] call ticket')
      //fetchMessages()
    })

    fetchMessages()
  }

  const authResponse = await auth()
  access_token = authResponse.access_token
  refresh_token = authResponse.refresh_token

  doConnect()
}

alguem pode me ajudar?
