It seems like there's an issue with the PostgreSQL connection. The error message indicates that the connection to the server cannot be established. This might be due to a misconfiguration or a firewall blocking the connection.

To troubleshoot the issue, I'd recommend checking the following:

1. Check the PostgreSQL server status to ensure it's running and accepting connections.
2. Verify the server's IP address and port number to ensure they match the ones specified in the connection string.
3. Check the firewall settings to ensure it's not blocking the connection.

If the issue persists, you may want to try resetting the PostgreSQL connection or seeking assistance from a database administrator.
