A video was not being authorized due to token failure.
Get the time stamp from when the token is generated. Knowing the expiration time and the generation time stamp, make sure the times are as expected. Compare the server time to a 'current time' service.
The issue could be that the expiration date is commonly generated using your server time. If there is a sync problem there, the expiration time will be wrong.
If all is good and you still have a problem, please create support case and provide all the information: - Request generation time" - Expiration time. - Full Token.
