Troubleshooting Video Performance
"No playable sources found" error message
The appearance of buffering when refreshing in Chrome
Chrome enforces rules that determine whether or not a video can autoplay on page load. Chrome may prevent a video from automatic playback, and this may cause the buffering icon to show in the video player. As a workaround, you can pause and play the video, playback will then start. Once Chrome "trusts" the Linux Academy website, this issue will no longer occur. We are currently looking into solutions for this issue.

Typically this error will be associated with your browser, network, or device. If you receive this error, please try the following steps:
- Clear your browser cache, log out, close your browser, and then log back in and retry the video(s) that had issues.
- Try running your browser in 'Incognito' mode. This can sometimes disable 3rd party browser extensions that can cause performance issues.
- Disable any VPN or proxy network connection
- Try from a different network location (if at work, try from home for example)
- Change to Google's Public DNS Servers (22.214.171.124 and 126.96.36.199), this will force your connection down a different path.
- Reboot your computer.
- Check for any available updates for your computer and reboot again.
