Nevermind. Fixed it. Apparently laravel elixir was turned on and I had css builds, so had to put fonts into /public/build.

i've just signed up to share another solution that i found, juste copy the font files (glyphicons-halflings-regular.*) to /public/fonts/bootstrap/ (you have to create the two ending folders) It worked for me using laravel 5.3, and using the default setup made with php artisan make:auth

How i found it ? I've juste checked the app.css file with my browser's developer tools, and searched for "glyphicon" and found a line "font-family:'Glyphicons Halflings';src:url(../fonts/bootstrap/glyphicons-halflings-regular.eot) "

So i figured out that i needed to put the fonts in the specified folder.

Hope this helps someone

Yeap you just helped me @ nzomedia
