  • It's possible that this is an authorization issue with the Azure Storage service. What happens if you retry after a wait of, say 30 seconds? If that doesn't help, please share more details on how you are creating the locators. We may need to look at the calls you are making to our service - please open a support ticket with the relevant details (Media Service account name, region used, list of API call(s) made, approximate time/date/timezone the calls were made).

    If you can't submit a ticket, you can send those details to
