# 17582: Status callback unreachable

Log Type: APPLICATION

Log Level: WARNING

## Description

Twilio couldn't connect to the configured callback URL after all retry attempts, so it couldn't deliver the transcription status event. The transcription itself is unaffected; only the status notification failed.

### Possible causes

* DNS resolution failed for the callback host.
* A firewall blocked the connection from Twilio.
* The server behind the callback URL was down.

### Possible solutions

* Verify that the callback URL resolves and is reachable from the public internet.
* Allow Twilio's IP addresses through your firewall.
