Routes.php :

use App\User;

Route::get('/', function(){
    User::create(['first_name' => 'moti']);
    return view('welcome');
});

The error i get :

PDOException in Connector.php line 55:

SQLSTATE[HY000] [2002] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

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 should I do to connect ?

What am I missing ?

I am using Laravel 5.1

Solution

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.
