First attempt at using default mitmproxy with my local site failed, SSE seems not to come through. Is there something I should set somewhere?

This testpage should show updates on wikipedia articles, but is just waiting for connection.

      var source = new EventSource('https://stream.wikimedia.org/v2/stream/recentchange');
      source.onmessage = function(event) {
        document.getElementById("stream").innerHTML += event.data + "<br>";
      };
    </script>
