Class App\Http\Controllers\Admin\AdminController does not exist does not exist

Hello All,

I am getting the following error:

Class App\Http\Controllers\Admin\AdminController does not exist

I have tried doing composer dump-autoload,

Here is my controller:

<?php

namespace App\Http\Controllers\admin;

use Illuminate\Http\Request;

use App\Http\Controllers\Controller;

use App\model\Admin;
use Auth;


class AdminController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */

     public function __construct()
    {
      $this->middleware('auth');
      $this->adm = new Admin();   

    }


    public function index()
    {
        //echo $request->user()->type;
        $user   = Auth::user();
        $role   = $user->role;

        $total_user = $this->adm->getTotalUser();
        $total_comment = $this->adm->getTotalComment();
        $total_blog = $this->adm->getTotalBlog();
  
        return view('admin.dashboard', array('total_cmt' => $total_comment, 'total_user' => $total_user, 'total_blog' => $total_blog,'role' => $role));

    }

       return redirect('admin/settings')->with('message','Data has been saved.');

            $rows = $this->adm->getallcommentbyUser($userid);
        }

    public function deletecomment($id){
        $rows = $this->adm->deletecomment($id);
        return redirect('admin/comments')->with('message','Data has been deleted.');

    }

    public function editcomment($id){
       $row = $this->adm->getcomment($id);
       $blog = $this->adm->getblog($row[0]->blog_id);

        $this->adm->updatecomment($request);
        return redirect('admin/comments')->with('message','Data has been updated.');
    }
}

What could be the reason? Just for informing, The code works completely fine on XAMPP. This error comes to me only in live server running PHP 7.1 in Cpanel through WHM
