I have my routes.php as follows:

<?php
$approutes =function (){

    Route::group(['middleware' => 'auth'], function(){
        Route::get('/', 'AdminController@index');
        Route::get('profile/{user}','ProfileController@index');    
        Route::post('profile/{user}/update',array('as' => 'profile.update','uses' => 'ProfileController@update'));    
        Route::resource('posts','PostsController');    
        Route::resource('tags','TagsController');    
        Route::resource('health','HealthController');    
        Route::resource('health-categories','HealthCategoriesController');
    });

    Route::controllers([
        'auth' => 'Auth\AuthController',
        'password' => 'Auth\PasswordController'
    ]);
};

$siteroutes =function (){
    Route::get('/', 'SiteController@index');
};

Route::group(['domain' => 'my.xxxx.com'],$approutes);
Route::group(['domain' => 'my.xxxx.dev'],$approutes);

Route::group(['domain' => 'www.xxxx.com'],$siteroutes);
Route::group(['domain' => 'www.xxxx.dev'],$siteroutes);

In my development .dev domains it is ok.

BUT when i tried to put it online in the .com domain all references from link_to_action (and possibly from every other route function) defaults to .dev domain.

I cant figure out what is happening.
