WebSocket connection failed: Unknown reason

tammersaleh commented 4 years ago

When I try to test this plugin using the demo WebSocket server at https://reveal-js-multiplex-ccjbegmaii.now.sh/token, I get a WebSocket connection to 'wss://reveal-js-multiplex-ccjbegmaii.now.sh/socket.io/?EIO=3&transport=websocket&sid=zaN_EvhrIjihGrDOCfvj' failed: Unknown reason error:

I've downloaded multiplex locally and am using it like such:

    <script src="//cdnjs.cloudflare.com/ajax/libs/socket.io/2.2.0/socket.io.js"></script>
    <script src="assets/reveal.js-4.0.2/dist/reveal.js"></script>
    <script>
      Reveal.initialize({
        plugins: [ RevealMarkdown, RevealHighlight, RevealNotes ],
        multiplex: {
          secret: '15922463425415769872',
          id: 'aba4830d9748420c', // Obtained from socket.io server
          url: 'https://reveal-js-multiplex-ccjbegmaii.now.sh' // Location of socket.io server
        }
      });
    </script>
    <script src="assets/multiplex/master.js"></script>
  </body>
</html>

I got the secret and id values from https://reveal-js-multiplex-ccjbegmaii.now.sh/token#

I have no experience with WebSockets (or Zeit, and very little with Javascript, for that matter). Any tips on debugging this would be greatly apprecaited.

Now the deployment referenced here (and in the README) is no longer available at all.

We've deployed a new demo server, see https://github.com/reveal/multiplex/issues/2#issuecomment-683667435
