here is my controller code that redirecting to the route:

.....

 return redirect()->route('admin.index.get')->withInput($request->only('admin', 'remember'));

.....

Here is my routes.php:

Route::group(['middleware' => ['auth','roles','custom-throttle','web'],'roles' => ['administrator'],'prefix' => 'admin', 'as' => 'admin.'], function() {

    Route::controller('/', 'AdminController', [

        //Basic
        'getIndex'                      => 'index.get'


    ]);


});

And i have AllowOverride All in httpd.conf, and Vhost.

What is wrong ? why its not working?

Answer 1

So, after lot of waisted time... i found the problem, hope it will help to anyone in the future.

Im using AWS Elastic Beanstalk, I upload zip file with my project version to my Elastic Beanstalk environment and the EB unzip it and uploading to my EB instance/s, this way in case that i have more then 1 instance (server) to my app , i dont need to upload version to each one of then separately, all the instances connected to a Load balancer that redirecting the requests flow to my app.

what happened is that in my env file configuration the session driver was "file" type, meaning its saving all the sessions locally in the storage folder in the project location (meaning on the server), the problem was when i was trying to log in, the session was created but then i was getting response from another instance (because the Load balancer) and of course there was no session there...

so, for anyone that will ever face this specific problem, just change the session driver to memcached / redis / database
