# 45005: Service Unavailable

Log Type: TWILIO

Log Level: ERROR

## Description

Twilio could not complete the request because the Flex service or a dependent Twilio service was temporarily unavailable. This error usually indicates a transient platform issue or a timeout while processing the request.

### Possible causes

* The Flex service was temporarily unavailable
* A dependent Twilio service did not respond in time
* The request timed out while Twilio was processing it
* A temporary internal service disruption affected the request

### Possible solutions

* Retry the request after a short delay
* Use exponential backoff if you retry requests automatically
* Check whether the issue affects a single request or multiple requests in your workflow
* Review your application logs to confirm the request parameters and timing
* If the problem continues, contact support with the request details and timestamps
