Ensure that the TCP/IP Port specified for the SQL Cluster in the ServerApp.properties file matches the port assigned in the TCP/IP Properties in your SQL Server Configuration Manager.

Background:
When QPS Server launches, it checks the port assigned in the TCP/IP Properties in your SQL Server Configuration Manager. When this process is executed, the values listed are used to update the QPS Server's SeverApp.properties file with the same port number. The default port number used in SQL Server is 1433
