Firewalls are put in place to protect users machines in case of an unauthorised connection/intrusion, however this can sometimes cause issues accessing content on the web due to oversensitivity of the settings or blocking particular web addresses.
In the case of YUDU Publisher, two domains are primarily used that should be placed on the white list/DMZ/'allowed' section of your firewall in order to ensure the best experience using the system:
- content.yudu.com - This domain hosts live content as default
- publisher.yudu.com - preview/proofing links are hosted here
Consult the user manual or documentation received with the firewall software/hardware in order to best understand how to ensure smooth access.
