Greetings!
The 503 error when trying to download the TTS license for Azure speech disconnected containers occurs because the NTTS container versions 2.19 and earlier are no longer supported as of February 29, 2024. This is expected behaviour. To resolve this issue, you need to update your NTTS containers to the latest version. After updating, the license download should proceed without issues. For more information and detailed steps on updating your containers, please visit: Azure Speech Service Containers.
Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
