I'm using Laravel 5.4 as an API. I have a routes set up for login and registration like so:
// Authentication routes...
Route::put('user', 'Auth\AuthController@changeUserName');
Route::post('login', 'Auth\AuthController@login');
Route::post('register', 'Auth\AuthController@postRegistration');
trying to login or register I create a post request with the required input I'm supposed to get 200 success response along with a JWT authorization header. And that works very well on my local machine: (Fedora 25, Apache/2.4.25, PHP 7.0.15) However on my production server (Ubuntu 14.04, Apache/2.4.7, PHP 7.1.2-3) I'm getting the above error.
Note of course that it's the same exact code. (I re-cloned the project just to be sure).
