Why each option
Port 1433 is the default TCP port for Microsoft SQL Server, which Citrix Studio requires to connect to the site configuration database.
Port 443 is used for HTTPS traffic, such as web-based management interfaces, not for SQL Server database client connections.
Microsoft SQL Server listens on TCP port 1433 by default for client connections. Citrix Studio communicates directly with the SQL Server instance that hosts the XenDesktop site database, and a firewall rule blocking port 1433 would prevent Studio from establishing that database connection, resulting in the communication failure described.
Port 1494 is the default port for the Citrix ICA protocol used to carry user sessions between clients and VDAs, not for database communication.
Port 27000 is used by the Citrix License Server for license checkout and management traffic, not for SQL Server connectivity.
