The captured video or audio from my test session failed to upload properly or was corrupted. What happened?

For security and test review reasons, all video and audio from your test must be uploaded and accessible. If any video or audio is missing or corrupted, your test will be invalidated.

  • Close all other programs running on your computer.

You can type “internet speed test” into most search engines and find a quick and free way to test your speed.
