The application could not reach the database server.

This usually means there is a network issue, or the database server is not running or is unreachable.

Here's what you can check:

1. Verify that the hostname (IP address or domain) and port in your .env file's MONGODB_URI are correct.
2. Ensure your database server is running and accessible from the internet.
3. Check that your server's firewall is configured to allow incoming connections on the correct port.
