Determine if your environment’s causing the issue
To determine whether your device, settings or internet connection may be causing the problem, please try watching another lecture or course (if you are only enrolled in one course, steps on how to preview a course can be viewed here).
If you’re able to watch other lectures without any problems, this indicates there is a technical issue with the original video. Please contact support so our team can investigate further and report the issue.
If you’re encountering playback issues with other lectures, however, then please try the troubleshooting steps outlined below.
Troubleshooting issues with your course playing environment
If you’ve determined the problem is due to an issue with your course playing environment, please do the following:
- Try watching the original lecture in an incognito window.
- If the video plays without issue, try checking your extension, plugin or firewall program on your device to see if it needs to be reconfigured or disabled.
- If you have a lot of browser tabs open, close most of them except the one you’re using to watch the course.
- Check your browser version and update it if needed.
