# 51113: Twilsock: Product usage is not enabled

Log Level: ERROR

## Description

Twilsock rejected the connection because the product you are trying to use is not enabled for your Account or API credentials. Twilsock is used by Twilio client SDKs to maintain a persistent connection for products such as Conversations, Sync, and Programmable Chat.

### Possible causes

* The Account SID or API Key you used does not have access to the Twilio product requested by the SDK.
* The product is not enabled for your account.
* The access token includes a grant for a Twilio product that is not enabled or not configured for your account.
* The application is connecting with credentials from the wrong account or subaccount.

### Possible solutions

* Verify that you are using the correct Account SID, API Key, and access token for the Twilio account that should access the product.
* Check that the product in your access token grant matches the product you have configured in your application.
* Confirm that the product is enabled for your account in Console before attempting to connect.
* If you recently changed accounts, subaccounts, or credentials, generate a new access token and reconnect.
* If you need access to Conversations, Sync, or another Twilio client SDK product and it is not enabled, follow the product setup documentation or contact Twilio Support through the Help Center.
