How Do I Fix The M3u8 Access Denied/Cross Domain/404 Not Found Error?

 This issue is likely due to a firewall your network has in place, try these options as a quick solution:

• View the webcast from an alternate location

• View the webcast on your mobile device, on cellular data. (note: data charges may apply)

• Alternately, ask your IT administrator to white-list this domain: ce21media.streaming.mediaservices.windows.net

Note that this method will require you to reboot your computer to ensure the changes work correctly.
