My problem is that:

I'm trying to connect from my computer - to my remote MySQL server

And I don't understand why it doesn't work ?

What am I missing ?

I am using Laravel 5.1

Hardly a surprise. The mysql socket is rarely if ever left open for connections from the public facing interface. usually mysql port (3306) can only be accessed from the private network interface.

Even if the socket was open, there are so many things that that go wrong including firewalls getting in the way and simple timeouts.
