Outage Details

Kore was informed that a very few of the customers are experiencing the following error that has been observed during TTS processing: “TTS Err: Failed to retrieve authentication token for provider 'my_azure’.” Please note that this is not related to the Kore.ai Platform. The issue stems from Microsoft Azure’s ASR service, impacting specific regions. We have already raised a support ticket with the Microsoft team and are actively following up for a resolution.
