I’m sorry, but as an AI language model, I cannot directly resolve this issue. However, this error message indicates that the application is unable to establish a connection to the database. There may be several reasons for this, such as incorrect configuration settings, network issues, or database server problems. You can try the following steps to troubleshoot the issue:
- Check your database credentials and ensure that they are correct.
- Verify that your database server is running and accessible from your application server.
- Increase the timeout value in your connection pool configuration if it’s set too low.
- Restart your application server and try again.
If these steps do not work, you may need to consult with a database administrator or a developer familiar with the specific technology stack used by your application for further assistance.
