403 Access Denied

[Mian Muhammad Usman]

I implement the Entrust Roles and Permission on my laravel application 5.6.
I followed the complete method from here https://github.com/Zizaco/entrust

but after the complete implementation. I face "403 Access Denied" when try to login with admin.

If I try to login as regular user, then immediately redirect to login page, without logged in session.

Please guide me
