following is the code which I used for export functionality

```
public function export(){
        $users = DB::table('users')->where('user_type','Farmer')->orWhere('user_type','Dealer')->select('id','name','middlename','surname','mobile','state','district','taluka','user_type')->get()->map(function ($item, $key){
            return (array) $item;
        })
        ->all();

        $usersArray = []; 
        foreach ($users as $user) {
             $usersArray[] =$user;
        }

        Excel::create('users',function($excel)use($usersArray) {
            $excel->setTitle('users');
            $excel->setCreator('Laravel');
            $excel->setDescription('users file');
            $excel->sheet('sheet1',function($sheet)use($usersArray) {
            $sheet->fromArray($usersArray,null,'A1',true,true);
            });

        })->download('xlsx');
    }

```

This code is working fine on localhost,no issue at localhost, But on server it is showing error that "This site can't be reached", I am unable to figure it out that what is the issue on server. 
I even try some other solutions on stackoverflow but unable to work.
