+If you do not need to use a public endpoint of a TiDB Serverless cluster, you can disable it to prevent connections from the internet:

+
+2. Click **Networking** in the left navigation pane and click **Disable** in the right pane. A confirmation dialog is displayed.
+
+3. Click **Disable** in the confirmation dialog.

+After disabling the public endpoint, the `Public` entry in the **Endpoint Type** drop-down list of the connect dialog is disabled. If users are still trying to access the cluster from the public endpoint, they will get an error.

+You can re-enable the public endpoint after disabling it:
