Video errors can be caused by a number of factors, including network issues, server issues, or the file uploaded by the instructor. If you are experiencing any difficulty watching videos, here are a few steps to try resolving the issue:

  • Confirm your internet connection
  • Refresh your browser
  • Close and reopen your browser
  • Attempt to play the video in an Incognito or Private window by clicking your browser's menu button and selecting "New Incognito/Private Window"
    • If the content successfully loads in the new window, this is an indicator that a browser extension is likely preventing the content from loading.
  • Clear your browser’s cookies and cache (
  • Confirm that Flash is enabled for your browser 
  • For troubleshooting Video Error Code 232011 or "Cannot load M3U8: Crossdomain access denied" error messages, work with your IT network team to check on your firewall status.
    • If you have a firewall, you can allow a particular HTTP header:
      Access-Control-Allow-Origin: *
