Lookup the correct connect string in your Azure Portal.

Or access is blocked by a Firewall, either a local or on Azure.

Hi @Microsoft Tech for Social Impact

To get the meaningful networking error message, please run the Azure SQL-Connectivity-Checker.

The PowerShell script will run some connectivity checks from your machine to the server and database.
