# How to re-authenticate connection

||| Note: only the administrator (user with an admin role in Klippa) of the Klippa account can re-authenticate the connection 

In certain cases, it is necessary to perform a re-authentication, such as when an integration error occurs while retrieving data or when no data is displayed when using the division picker or during booking in the booking rules. Re-authentication may also be required if there have been changes made to the user who established the connection.

**Examples:**
* Error message: Could not get book suggestions
* Error message: Integrations call error

### Solution
We recommend reconnecting to an user (ideally permanently associated with the organization) who has sufficient rights.

||| Note: You must have the License Management role to manage apps for all users. Verify that you and other users have access rights to the administrations for which you want to manage app access. **Refer to** ''Your rights''

1. Navigate to **Settings > Business > Connections > Re-authenticate.**
