AzureException Timeout

Error message

AzureException Timeout - {message}

What it means

Azure-specific status mapping: an upstream Azure exception with HTTP 404 is re-raised as NotFoundError — usually an unknown deployment, wrong api-version path, or a resource that was deleted.

Solutions

1. Increase the request timeout or retry; the Azure endpoint timed out.
2. Check Azure service health and network latency.

When it happens

Trigger: Thrown at litellm/litellm_core_utils/exception_mapping_utils.py:2004 when the library encounters an invalid state.

Common situations: See trigger scenarios.

Understand the failure class
