# 60401: Network Error

Log Type: APPLICATION

Log Level: ERROR

## Description

This error indicates that Verify could not communicate properly with the API while processing your request. Retry the request as a transient failure first, then confirm that the request itself is valid if the error continues.

### Possible causes

* A transient communication failure occurred while Verify was calling the API.
* An active Twilio incident or degraded service is affecting API requests.
* Your SDK or HTTP client is introducing the failure. If the same request succeeds with `curl`, the problem is likely in your SDK-side integration.

### Possible solutions

* Retry the request after a short delay. If you automate retries, implement exponential backoff.
* Validate the Verify request before retrying. Send the request to the Verify Verifications endpoint, provide a valid `To` value, and use a supported `channel`. Phone numbers must be in `E.164` format.
* If you use a helper library or SDK, send the same request with `curl`. If the request works with `curl`, fix the SDK-side request generation. If it fails in both places, contact Support.
* When you contact Support, include the `Twilio-Request-Id` header from the failed response. Also check the Twilio status page for any ongoing incident that could affect API requests.
