If your users access the Udemy for Business site from inside the company's network, and they experience significantly degraded performance (i.e., playback delays) while streaming videos, the video streaming domains Udemy for Business utilizes should be whitelisted.
To ensure your users can view Udemy for Business videos without any issues, please have your organizations’ IT whitelist the following video streaming domains on your network firewalls/gateways:
- adaptive-streaming.udemy.com
- udemy-assets-on-demand.udemy.com
- udemy-assets-on-demand2.udemy.com
- udemy-images.udemy.com
- h.udemycdn-a.com
- a.udemycdn.com
- a2.udemycdn.com
- i.udemycdn.com
If the issue persists after your organization’s IT has whitelisted these domains, please advise your users still encountering the issue to reach out to Udemy for Business Support and have them provide our team a HAR file. The information in the HAR file will help our engineers in determining what the issue is so they can start working on a resolution.
