Работа на localhost, на домене не работает. Время соединения вышло?

Сайт работает на localhost: 33333, но если я запускаю my.domain.com:33333 или my.domain.com не работает. (Connection timeout)

В чем может быть причина?

<VirtualHost *:33333>
ServerName my.domain.com
DocumentRoot /var/www/vtigercrm/
ErrorLog /var/log/apache2/vtiger.my.domain.com.error_log
CustomLog /var/log/apache2/vtiger.my.domain.com.access_log combined
<Directory /var/www/vtigercrm>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
</VirtualHost>

[ 116] вывод:

/etc/apache2/ports.conf:Listen 33333
