Hi Davide,
Can you try connecting to http://localhost:8080 instead of https://localhost:8080?
Cheers,
Jeffrey
Edit1: Automatically reload for localhost can be changed:
Go to chrome://net-internals/#hsts. Enter localhost under Delete domain security policies and press the Delete button.
Now go to chrome://settings/clearBrowserData, tick the box Cached images and files and press click the button Clear data.
I tried to, but Chrome automatically redirects to https.
But, if I open http://localhost:8080/ in an Incognito window, it actually works and loads my app.
So I assume this was just some Chrome quirk!
