This issue occurs when clicking into an attached video file within your Centercode implementation (which then opens the video in a new tab within your browser), watching the video, then attempting to download the video from the browser's video player.
While viewing the video, there's a time-limited authorization window where downloading is allowed. The time window is short due for security purposes. Once the time period is exceeded, you will receive a "Failed - Forbidden" message.
