laravel liver server error Class 'App\models\Unioun' not found

I am using laravel latest version, i have build a relation with User and Division models

    public function user()
    {
        return $this->hasMany('AppmodelsUser', 'id');
    }
        public function division()
    {
        return $this->belongsTo('AppmodelsDivision', 'division_id');
    }

And in blade view

  class="">Division</td>
  <td class="">:</td>
  <td class="">{{Auth::user()->division == null ? 'Not define' : Auth::user()->division->name}}

Local server working good, but live server showing error

Class 'AppmodelsUnioun' not found
