I just uploaded my laravel project to namecheap hosting and i got this error when trying to log into admin page Class App\Http\middleware\AdminMiddleware does not exist

AdminMiddleware.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class AdminMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(Auth::user()->usertype == 'admin')
        {
            return $next($request);
        }
        else
        {
            return redirect('/');
        }
        
    }
}
