I got it working by:
changing rcron.php
$config = array(
# 'url'=>'http://ticket.mywebsite.com:8080/support/api/tasks/cron',
'url'=>'http://ticket.globevoices.com:8080/api/tasks/cron',
'key'=>'BC1B9FFF89876B7BC734037615A817E2'
);
Adding the API using a local Server IP (in my case 192.168.6.17)
To check if it works I enabled Setting/System/Default Log Level: DEBUG and checked Dashboard/SystemLogs
I hope it helps anyone.
