# Challenge Expired

> The authentication challenge has expired

## Cause

The challenge Guile issued for this sign-in or verify step has expired. Guile
will not accept the old challenge payload; no new session tokens are issued from
it.

## Fix

Create a new challenge with
[create an authentication challenge](/api-reference/challenges/create-an-authentication-challenge)
(or the registration challenge path you use), complete verification, then call
the verify operation again.

## Retry safety

Not retryable

## Raised by

These operations can return this problem:

* [Verify the current email address](/api-reference/email-verification/verify-the-current-email-address)
* [Verify authentication](/api-reference/challenges/verify-authentication)
* [Verify customer registration](/api-reference/registration/verify-customer-registration)
