Connectivity Troubleshooting

Most companies have firewalls, proxy servers, intrusion detection and prevention and/or web filtering devices in place as a mechanism to maintain a level of security and reliability of their network infrastructure. In some instances, these mechanisms may require adjustment by your company's IT Infrastructure team to ensure a quality user experience for the rich media and interactive features of the platform.

The list below includes hostnames and ports used by the platform as well as the corresponding application functions they provide. If you are having issues with the interactive and/or rich media features of the platform, this information can be used by a network administrator to help resolve them. This page is updated when necessary so please bookmark it for future reference.
