How It Affects Your App
The impact of this error is that the application will not be able to connect to the MySQL server. This means that any data stored in the MySQL server will not be accessible to the application, and any queries or commands sent to the MySQL server will not be executed. This can lead to data loss, as well as a disruption of the application's functionality. Additionally, the application may not be able to perform certain tasks that require access to the MySQL server.
