By default, CA/DA uses TCP/IP Port 1433 to connect the SQL server. When this port is changed for the SQL instance to another value, the connection to the SQL server will failing.

Determine what port is configured for SQL instance and provide it while creating Configuration DB in the format: SQLServerName, Port_Number.  For example, if the default SQL listener port of 1433 is changed to 60122 and the SQL Server name is EVSQL, the SQL Server name to specify would be EVSQL,60122 as shown in the screen shot below.
