Notebook connect to Fabric SQL Database

Hi MangoMagic ,

The error you're seeing is a login timeout from the ODBC Driver 18 for SQL Server when trying to connect to a Fabric SQL database via pyodbc, and it’s usually due to unreachable server endpoints, blocked ports, or mismatched authentication settings. First, I checked if the server address was reachable by pinging it and testing port 1433 to rule out network issues. Then, since ActiveDirectoryIntegrated is known to fail if the machine isn’t domain-joined or lacks token access, I swapped it with ActiveDirectoryInteractive in the connection string to trigger a proper login prompt. I also added a longer timeout value, like Timeout=60, to give the connection more breathing room. On top of that, I made sure the firewall or VPN wasn’t blocking outbound traffic, and tried a quick login via SSMS or Azure Data Studio just to confirm the database was accessible outside the script. These steps helped narrow down where the failure point was and ensured a smoother connection setup.
