Laravel 5.2: Ajax login not working on live server, but working fine on localhost. Auth not working on live server

I am making a project in laravel 5.2 I have an issue.

this is a school management system where admin/teachers/students login to see their dashboard.

I have made a login page where username and email is given and users can login.

I have my own table for site users named "systemusers".

login is working fine on localhost but its not working on live server.

Auth is not working and users are redirected to login page again.
