Subscribing to new blocks doesn´t work [ROPSTEN]

Question

I'm trying to subscribe to newBlockHeaders on the ropsten network, but it does not seem to work. The following code works for mainnet but not ropsten. Any ideas?

const Web3 = require('web3')
const webSocketProvider = new Web3.providers.WebsocketProvider(
  'wss://ropsten.infura.io/ws/v3/<MY PROJECT ID>'
)
const web3 = new Web3(webSocketProvider)

async function notify() {
  var subscription = web3.eth
    .subscribe('newBlockHeaders', async function (error, result) {
      if (!error) {
        console.log(result)
        return
      }
      console.error(error)
    })
    .on('connected', function (subscriptionId) {
      console.log('Connected!')
    })
    .on('error', console.error)
}

notify()
