Persistent video buffering could be due to a full cache, an outdated browser, a slow Internet connection, and more. If you're trying to play a course and are experiencing playback issues ("buffering"), we recommend trying the following troubleshooting steps:
- Verify that your device and browser meet our General System Requirements.
- Try a hard refresh of the page (Windows: Ctrl + F5, Mac: Cmd + Shift + R). Sometimes simply refreshing the page does the trick!
- Run an Internet speed test. For the best viewing experience, we recommend a connection download speed to be 15 mbps or higher. Test your connection speed now
- Clear your browser cache. For step-by-step instructions on clearing your cache, click here.
- Make sure your browser is up-to-date. Running an outdated version of the browser may be causing the streaming issues. For links to download the latest versions of each browser, click here.
- Try switching to a different browser (but make sure it's the latest version!)
- Try adjusting the resolution of the video from within the course center.
- Hover your mouse over the video screen and click on the cog wheel icon
- If your video is playing in High resolution, try selecting Medium. If that doesn't help, try switching to Low.
- Try another device. If you're watching on your tablet, for instance, try watching on your laptop (and vice versa). See if another device is giving you the same issue.
