# 91308: Destination endpoint did not respond in time

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio records this error when Data Destinations establishes a connection and transmits an event to your destination, but the destination fails to return an HTTP response before the timeout limit is reached.

Because Twilio did not get a response from your destination, Twilio will automatically retry event delivery per retry policy. To prevent duplicate processing when retries occur, your destination should treat Data Destinations delivery as at-least-once delivery and deduplicate incoming events using the unique Event ID.

### Possible causes

* The destination executes time-consuming operations, such as synchronous database writes, complex computations, or downstream API requests, before returning an HTTP response.
* A service downstream from your handler experienced high latency or a timeout.
* High incoming event volume exhausted available server resources.

### Possible solutions

* Acknowledge incoming payloads immediately with an HTTP 2xx status code, offloading long-running operations to a background queue or worker process.
* Monitor your destination response latencies to identify transient slowdowns under load.
* Ensure your destination is sized appropriately for peak concurrency.
