- cdn-thumbs.viddler.com
- medbridge-vfs.cdn-ec.viddler.com
If there is a loading symbol on the screen of the video player, it may mean that you need to clear your cookies and cache. Directions specific to your browser and more troubleshooting tips, can be found via this link: Technical Requirements
