Took me a while to figure it out. It was, at first, looking like it was not working at all. I had just installed it and configured like I use to do with Pusher, then added the proper ports and so, but nothing was hitting the terminal log, so I finally opened the dashboard, then magically events started to show up on the terminal and the front end.
So I disconnected the dashboard, closed the page and created and, after a while, created a new event, which again was not showing up on terminal, so I opened the dashboard and voilá! there was it, working.
Then I moved to my home machine, git pull, composer install, migrate, npm run watch, opened the interface, it connected successfully to the server, but not a single event is showing in terminal log, all I get is ping and pongs.
