Hey, sorry you're running into the issue. I just tried the discord link and it appears to still be working, but no worries.
I have had a couple macOS users run into this issue with the plugin. I am working on an update that will likely address the issues however you can test if it's working by opening the plugin in Ableton, opening your web browser, and navigating to http://localhost:8422/data. If it doesn't load any information then likely something is blocking the connection.
