Run PubSub example locally

The current URL in my dev console is http://localhost:8080/, I’ve just changed it in the PubSub example and reload. But still getting the redirect mismatch error

It it’s correct in both places, should also give it around 5 minutes in case of any caching on Twitch’s side that can result in a “mistmatch” error.
