# How to Fix Channel Verification Expiration Errors

When a channel's verification token expires, you will not be able to proceed with your broadcast until the authorization is renewed.

***

#### Channel Verification Expired

{% hint style="danger" %}
Error Message: Your channel verification information has expired. (Error code: 27000)
{% endhint %}

#### Cause

The verification token for the channel has expired. Token expiration can occur in the following two cases.

* The token API validation fails because the channel has not been used for streaming for an extended period of time
* The user has manually removed PRISM Live Studio's access authorization from the platform's website

#### Solution

1. Remove the affected channel from PRISM Live Studio, then click Add Channel to log in again and renew the authorization.
2. If the issue persists after reconnecting, click the PRISM info (i) icon at the bottom right of the app and select Contact Us to submit your inquiry.
